Impact of prostitution on mental health

Young prostitutes in São Paulo, 2019

The Impact of prostitution on mental health refers to the psychological, cognitive, and emotional consequences experienced by individuals involved in prostitution. These consequences include a wide range of mental health issues and difficulties in emotional management and interpersonal relationships. Prostitution is closely linked to various psychological pathologies and affects not only those directly involved but also society at large. Studies have shown that both street and indoor sex workers have experienced high levels of abuse in childhood and adulthood, with differences in trauma rates between the two groups.

Women in prostitution experience a profound impact on their identity, encompassing cognitive, physical, and emotional dimensions, manifesting in health problems and difficulties in emotional management and interpersonal relationships. Prostitution, being strongly linked to psychopathology and social health, should be addressed as a medical situation that affects not only the individuals involved but also society at large, with psychological aspects.

Sex work involves the provision of one or more sexual services in exchange for money or goods. However, sex workers are not a homogeneous group. Street sex workers are often illegal, finding clients on the street and providing services in alleys or clients' cars. On the other hand, indoor sex workers operate in brothels, massage parlors, or as private escorts. Previous research has shown that both street and indoor sex workers have experienced high levels of abuse in childhood and adulthood, though indoor sex workers report lower rates of abuse and trauma compared to street workers.

There is a high prevalence of victimization in childhood and adulthood among sex workers, with secondary trauma disorders. Recurrent victimization, known as "Type II trauma," can cause pathological psychological changes that are difficult to classify. Proposed diagnoses include developmental trauma disorder for childhood and complex post-traumatic stress disorder (cPTSD) for adulthood, though these are not included in official diagnostic manuals.

There is a connection between prostitution and trafficking, organized crimes that reflect sexism, patriarchy, capitalism, and economic inequality. The physical consequences of sexual exploitation include sexually transmitted diseases, cervical cancer, chronic pain, liver problems, unintended pregnancies, eating disorders, concentration and memory difficulties, visual and hearing problems, fractures, and, in extreme cases, death. Psychologically, women suffer from low self-esteem, stress, pathological ties with control networks, social isolation, loneliness, extreme fear, hopelessness, and a lack of assertiveness in seeking support, resulting in trauma that alters their beliefs and perceptions, causing irreparable damage to their personal identity. These conditions are exacerbated by language barriers and other vulnerability factors, such as having suffered sexual abuse in childhood or being the main economic support for their family, which is exploited by pimps.

The effects on mental health are severe, with high rates of depression, anxiety, and post-traumatic stress disorder (PTSD) among those who sell sex, exacerbated by social stigma, discrimination, physical violence, and mistreatment by authorities. Studies in the United States and Canada reveal depression symptoms in 68% of these individuals and PTSD symptoms in nearly a third, showing higher rates than in combat veterans. Substance abuse is common, generally as a response to sex work rather than a cause, with most increasing drug use to cope with their reality.

The sex industry is a global business worth $57 billion annually, with the United States hosting the largest number of adult clubs in the world, employing over 500,000 people. Between 66% and 90% of women in this industry were sexually abused during their childhood. These women have higher rates of substance abuse, sexually transmitted infections, domestic violence, depression, violent aggression, rape, and PTSD compared to the general population.

The emotional effects of prostitution are devastating. Dissociation, a response to uncontrollable traumatic events, is common among prostituted individuals, similar to the response of prisoners of war. Research has shown that both indoor and outdoor sex work increase the risk of being assaulted. In outdoor sex work 82% of women reported being physically assaulted, and 68% reported being raped. In indoor settings, more sexual violence and threats with weapons were reported. Women in the sex industry frequently face multiple psychosocial stressors, limited resources, and a high rate of untreated health and legal problems.

Other studies that assessed the presence of psychological alterations in prostitutes, compared to non-prostitutes, also documented concentration and memory difficulties, as well as sleep problems (with an incidence of 79%), irritability (64%), anxiety (60%), phobias (26%), panic attacks (24%), compulsions (37%), obsessions (53%), fatigue (82%), and concerns about physical health (35%), and 30% of the sample reported a suicide attempt.

Context

They do not want to by Francisco Goya (1746–1828) depicts an elderly woman wielding a knife to defend a girl being assaulted by a soldier.

The consequences of being repeatedly bought and sold for sex with strangers result in a variety of medical issues, including malnutrition, pregnancy-related problems, old and new injuries from sexual assaults and physical attacks such as burns, broken bones, stab wounds, dental trauma, traumatic brain injuries, anogenital injuries (rectal prolapse/vaginal injuries), internal injuries, sexually transmitted infections, and untreated chronic medical conditions. Individuals in prostitution are subjected to multiple forms of violence, such as rape, sexual assault, emotional abuse, economic and physical abuse, food deprivation and sleep deprivation, and acts of torture by pimps, traffickers, brothel owners, and sex buyers. This results in cumulative psychological and physical trauma with lifelong impacts. Individuals in prostitution often experience stress and multiple traumas, such as physical or sexual abuse in childhood, the sexual exploitation itself, and homelessness, and may have difficulty remembering details of their lives due to traumatic brain injuries, cognitive impairment, repressed memories, or dissociation, largely caused by pimps, traffickers, and sex buyers. Reported psychiatric disorders include depression, anxiety, schizophrenia, eating disorders, sexual dysfunction, substance abuse, suicidal ideation or suicide attempts, self-harm, post-traumatic stress disorder (PTSD), and dissociative disorders.

Dissociation, a severe symptom related to trauma, is common and develops as a coping strategy in response to extremely painful, frightening, or potentially life-threatening events. Additionally, pimps and traffickers often control victims' access to medical care, allowing them to seek help only when injuries or illnesses are particularly severe or if their ability to earn money is affected, but often prohibiting preventive or follow-up care. The traumatic scars from this physical and psychological damage are permanent. Children trafficked for sex are the most vulnerable to medical and psychological harm. Entry into prostitution typically occurs during childhood and adolescence, with most initially lured by a "boyfriend" and/or "protector." While not all enter the sex trade through a pimp or trafficker, each encounter with a sex buyer puts the individual at risk of harm. Studies suggest that up to 50% of human trafficking victims seek medical care while in trafficking situations. The harmful effects of prostitution are reflected in the high rates of PTSD among survivors, with symptoms such as anxiety, depression, insomnia, irritability, recurrent memories, emotional numbness, and hypervigilance. Of 475 individuals in prostitution interviewed in five countries, 67% met the diagnostic criteria for PTSD, indicating that the traumatic consequences of prostitution are similar across cultures. Individuals in prostitution suffer extremely high levels of violence: 62% of women report being raped and 73% report being physically assaulted in the sex trade. Transgender youth in prostitution are over four times more likely to have HIV than those without such a history. The mortality rates for women in prostitution are 40 to 50 times the national average. Among known victims of fatal violence against transgender individuals in the U.S. from 2013 to 2018, 32% were in the sex trade, including many who died while in prostitution.

In "Prostitution and the Invisibility of Harm," Melissa Farley examines how the harms associated with prostitution are invisible in society, law, public health, and psychology. Farley argues that the invisibility of these harms originates from the use of terms that conceal the inherent violence of prostitution, as well as from public health perspectives and psychological theories that ignore the harm inflicted by men on women in prostitution. The author summarizes literature documenting the overwhelming physical and psychological harms suffered by individuals in prostitution and discusses the interconnection of prostitution with racism, colonialism, and child sexual abuse. Farley describes prostitution as a form of sexual violence that generates economic benefits for perpetrators and argues that, like slavery, it is a lucrative form of oppression. She highlights how institutions protect the commercial sex industry due to its enormous profits, and how these institutions, deeply rooted in cultures, become invisible. The author criticizes the normalization of prostitution by researchers, public health agencies, and the law, pointing out the contradiction in opposing human trafficking while promoting "consensual sex work." Farley argues that assuming consent in prostitution erases its harm and mentions that the line between coercion and consent in prostitution is deliberately blurred. The author proposes using terms that maintain the dignity of women in prostitution and criticizes the use of terms that disguise the inherent violence of this practice. Furthermore, the article documents the prevalence of physical and sexual violence in prostitution, citing studies showing high percentages of rape and physical assault among women in this situation. Farley also highlights the similarity between domestic violence and violence in prostitution, suggesting that treatment approaches for battered women are also applicable to prostituted women. Finally, Farley addresses the intersection of racism and colonialism in prostitution, pointing out how women are exploited based on their appearance and ethnic stereotypes, and discusses how child sexual abuse sets the stage for prostitution in adolescence and adulthood.

The chart shows that 87% of sex workers reported depressive symptoms, 54% severe depressive symptoms, and 74% suicidal thoughts. Additionally, 42% attempted suicide, 40% consulted a health professional in the last six months, and 79% of those consultations were for depression.

Research on the psychological impact associated with sex work, especially when exposed to violent situations, has shown that this activity is linked to the development of psychological stress and many other negative consequences in the short, medium, and long term. These consequences include depressive disorders, anxiety disorders, post-traumatic stress disorder, sexual trauma symptoms, and addiction disorders related to substance use.

The study by El-Bassel et al. (1997) showed that sex workers, compared to a control sample, had higher scores on the subscales of obsessive–compulsive symptomatology, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. To assess whether there was a direct relationship, the authors isolated other variables that could contribute to these higher values (differences in age, ethnicity, pregnancy, perceived risk of contracting HIV, rape, and substance use) and found a significant correlation between sex work and psychological stress.

In recent decades, the perception of mental health has changed significantly, especially among young people, who openly discuss depression, anxiety, and therapy. Mental health has become a recurring topic in popular culture, frequently featured in TV shows, movies, and songs, and has been the focus of numerous recently proposed and passed laws. This change is crucial to addressing the mental health of high-risk groups, such as people who sell sex. These individuals, often forced into this activity by survival, coercion, or deception, usually lack support networks and face economic precariousness, prior violence, and social marginalization, with a particular risk for LGBTQ+ and Black girls. Most who have sold sex started as minors, wanted to leave the sex trade, and suffered significant harm, as recounted by Esperanza Fonseca, a survivor who describes feelings of loneliness and deep sadness.

Prostitution can have profound and lasting psychological effects on those who engage in it. These effects can manifest in various disorders and symptoms that impact mental health and emotional well-being. Below is a detailed table exploring different psychological disorders associated with prostitution, describing their symptoms, reasons for occurrence, possible consequences, available treatments, severity, and prevalence among affected women.

Motivations for entering prostitution

«Generally here, they are all mothers and fathers of families, right? So, they are mothers by day and fathers by night, so it is difficult to save, right? Those clients are the ones who save us, right? They want fun, and we want money, right? That's all too.»

The study titled "Prostituição: um estudo sobre as dimensões de sofrimento psíquico entre as profissionais e seu trabalho" investigates the psychological difficulties that sex workers face due to moral judgments and adverse working conditions. It is based on the psychodynamic approach to work, which defines normality as a precarious balance between work constraints and the psychological defenses workers develop to maintain their mental health. Prostitutes can preserve a psychological balance despite the constraints and moral judgments they face in contemporary society. One of the research questions was why women choose prostitution as a profession. The answers indicated that economic necessity is the most important factor. The workers mentioned the need to support their children and families as the main motivations for entering prostitution. Additionally, some compared their earnings in prostitution with previous jobs where they earned much less for longer and more difficult working hours.

Sex workers develop mechanisms to manage their clients' desires and tastes, demonstrating their capacity for conception within their profession. However, they set clear boundaries on what they are willing to do, regardless of payment, to preserve their integrity and mental health.

Most research points to financial and social problems as the main causes of prostitution. Factors such as lack of job opportunities, family conflicts, and urgent economic needs drive many women into this profession. However, while the patriarchal system and gender violence are realities, there are also women who choose this profession by their own desires and will. Prostitution is not homogeneous and encompasses a plurality of desires and expressions of sexuality.

Many women enter sex work through false promises of marriage or well-paid employment in another city. Once in sex work, perceived stigma and sexual abuse by law enforcement officers, who often are also clients, convince them that no external help is available. These extreme circumstances force women to focus on survival rather than escape, which is essentially the core of Stockholm syndrome: a psychological attempt to survive physically in captivity. This behavior pattern is not limited to prostitution in brothels, as similar relationships are present in street, home-based, and caste-based prostitution. This has been a point of difficulty for rehabilitation programs against trafficking worldwide.

The role of motherhood affects the decisions and behaviors of women trapped in these situations. Motherhood becomes not only a natural and biological role but also a source of vulnerability and emotional strength. From a psychological perspective, the fear of losing their children or being unable to care for them adequately due to their sexual exploitation is one of the most influential factors in these women's psyches. This fear can generate intense anxiety and chronic stress, which in turn perpetuates the cycle of exploitation. The constant threat of separation from their children can trigger submissive and compliant responses, as women may feel trapped and without options. Anxiety and fear of abandonment not only affect their emotional well-being but also limit their ability to make rational and strategic decisions to escape their situation.

The need to protect and support their children can conflict with their desire to escape and seek a better life. This cognitive dissonance can be debilitating, as women may feel constantly torn between two equally painful options. The maternal instinct to protect their children can also motivate some women to seek escape from exploitation. But this protective drive may be hindered by the lack of resources, support, and viable options. Uncertainty about the future and fear of violent reprisals can paralyze their ability to act. From a psychological perspective, this can generate a state of learned helplessness, where women believe they have no control over their situation and that any attempt to change it will be futile or dangerous.

Risk factors

«One night, my monthly bills were soon due, I had no gas in my vehicle, I had maxed out my credit cards, and I had no food in my fridge. In nothing but an act of total brokenness and desperation, I contacted a brother and inquired about employment.»

Andrea Heinz, former prostitute.

Prostitution is primarily associated with poverty and, in most cases, is not a professional choice or vocation, but a way of monetizing the body due to lack of opportunities. It is directly related to social inequality and gender issues in the country. The main beneficiaries of this trade are pimps and those involved in managing trafficking and sex tourism.

Prostitution is often understood in the context of the traditional consumer risk model, where the consumed product is perceived as the agent carrying risks. However, in prostitution, the prostituted person is the "product" consumed, and it is they who are at greater risk, even though prostitution is sometimes erroneously described as "sex between consenting adults." Prostitution occurs because the prostituted person would not consent to sex with the buyer if they were not paid, which redefines the notion of consent and risk in this context. The traditional consumer risk model does not adequately apply to prostitution, where the prostituted person assumes significantly greater risks than the sex buyer or the pimp. A sex buyer interviewed explained that "being with a prostitute is like having a cup of coffee, when you finish, you throw it away." This perspective shows the dehumanization and objectification of prostituted individuals.

Prostitution is often the result of a combination of individual, social, and economic factors. Individuals who engage in prostitution do so due to a series of adverse circumstances that limit their options and increase their vulnerability to exploitation. Below is a list of risk factors that can contribute to a person falling into prostitution:

  • Poverty: The lack of economic resources is one of the main factors driving people to prostitution. The urgent need for money to cover basic necessities like food, housing, and medical care can lead to desperate decisions.
  • Lack of education: Limited educational opportunities restrict employment options, which in turn can push individuals toward prostitution as a way to earn money quickly.
  • Unemployment: The lack of employment or job instability can lead people to seek alternative means of income, including prostitution, especially in contexts where there are few formal job opportunities.
  • History of childhood sexual abuse: Sexual abuse during childhood is a common precursor to prostitution. Traumatic experiences can lead to vulnerability and the normalization of sexual exploitation in adulthood.
  • Domestic violence: Individuals who have been victims of domestic violence may turn to prostitution as a way to escape an abusive situation or to gain financial independence.
  • Lack of family and social support: The absence of a strong support network can leave individuals without emotional or financial resources, increasing their vulnerability to sexual exploitation.
  • Mental disorders: Mental health issues such as depression, anxiety, and post-traumatic stress disorder can make individuals more susceptible to exploitation in prostitution.
  • Previous experiences of exploitation: Individuals who have been trafficked or exploited for labor may be more vulnerable to falling into prostitution due to the continuation of the exploitation cycle.
  • Gender inequality: Discrimination and gender inequality can limit opportunities and increase women's vulnerability to sexual exploitation.
  • Displacement and migration: Displaced or migrant individuals, especially those without documentation, are particularly vulnerable to sexual exploitation due to their precarious situation and lack of legal protection.
  • Cultural and social factors: In some cultures and societies, social norms and expectations can contribute to sexual exploitation, either by stigmatizing victims or accepting prostitution as an economic solution.
  • Coercion and deception: Many individuals are forced or deceived into prostitution, either through human trafficking, false promises of employment, or direct coercion by pimps.
Risk Factors for Prostitution.

The risks associated with prostitution are numerous and well-documented. They include sexual harassment, rape and unprotected rape, domestic violence, physical assault, and psychological aftermaths such as post-traumatic stress disorder (PTSD), dissociative disorders, depression, eating disorders, suicide attempts, and substance abuse. The frequency of rape in prostitution results in extremely high rates of sexually transmitted infections, including HIV, with studies reporting an HIV prevalence of 93% in some prostituted populations. Family abuse and neglect often precede entry into prostitution. Physical, sexual, and emotional abuse during childhood is a common precursor, considered by many experts to be a necessary risk factor for prostitution. In one study, 70% of adult women in prostitution reported that childhood sexual abuse was responsible for their entry into prostitution. This abuse creates a cycle of victimization that impacts their futures and prepares them for exploitation in prostitution.

Poverty in Rocinha in Rio de Janeiro is one of the main triggers of prostitution in the city.

The fantasies of sex buyers drive the realities of prostituted individuals. Buyers seek to fulfill their fantasies through prostituted individuals, who must act according to the buyer's expectations. Failure to meet these expectations often leads to brutal violence. Objectification and dehumanization are intrinsic to prostitution, where prostituted individuals are seen as objects or products with economic value, facilitating their exploitation and abuse. Physical violence is a constant in prostitution. An occupational study noted that 99% of women in prostitution were victims of violence, with more frequent injuries than in occupations considered dangerous such as mining or firefighting. Poverty and duration in prostitution are associated with greater violence. In Vancouver, 75% of women in prostitution suffered physical injuries from violence, including fractures and head injuries.

The emotional effects of prostitution are devastating. Dissociation, a response to uncontrollable traumatic events, is common among prostituted individuals, similar to the response of tortured prisoners of war or sexually abused children. Dissociation is a necessary skill for surviving rape in prostitution, reflecting the dissociation needed to endure family sexual abuse. Dissociative disorders, depression, and other mood disorders are common among prostituted individuals in various settings. Prostitution and slavery share characteristics of dehumanization and objectification, resulting in a "social death." The prostituted individual is reduced to body parts and acts out the roles desired by buyers, suffering a systematic assault on their humanity. This objectification becomes internalized, causing profound changes in their self-perception and their relationships with others.

Sex buyers often understand the risks and consequences of prostitution but rationalize their behavior. Many acknowledge exploitation and economic coercion but continue to buy sex. Risk denial strategies, such as minimizing abuse or justifying payment, perpetuate exploitation.

Prostitution not only involves risks for prostituted individuals but also for buyers, who face legal risks, social stigma, and health risks. However, public attention often focuses more on the buyer's health than on the prostituted individual's, perpetuating the myth that prostituted individuals are vectors of disease. Public denial of prostitution risks is fueled by narratives from buyers and pimps that conceal violence and exploitation. This denial is similar to strategies used by the tobacco industry or climate change deniers, where harms are minimized, and exploitation is justified.

Government complicity sustains prostitution. The legalization and decriminalization of prostitution integrate this exploitation into the state economy, relieving governments of the responsibility to find employment for women. However, legalization does not eliminate the inherent risks of prostitution, as demonstrated by the recommendation for hostage negotiation training for those in legalized prostitution in Australia. Harm reduction approaches in prostitution, such as distributing condoms, do not address the root causes of the problem. Eliminating risk requires real survival options outside prostitution and a change in power structures that perpetuate exploitation. Survivor voices who have exited prostitution point toward obvious legal solutions. Sex buyers and pimps must be held accountable, and survival alternatives must be offered to prostituted individuals without criminalizing them. Several countries have adopted abolitionist approaches, penalizing sex buyers and providing exit services and job training for prostituted individuals.

Types of prostitutes

Street prostitute in Argentina

«There were 30 to 40 clients per day, men and women. My body endured 12-hour work shifts, and weekends lasted even longer. I needed painkillers to cope. From the first time, you become dead inside, different men touch you, and underage girls like me are fresh meat. They insulted me, hit me, spat on me, didn't respect me, and days, weeks, months passed like that... until it became four years.»

Karla Jacinto.

From a psychological perspective, prostitution presents a series of significant impacts that vary according to the type of sex work and the conditions under which it is carried out. Independent prostitutes, such as escorts and call girls, may experience lower levels of exploitation and have greater control over their working conditions, potentially mitigating some negative effects on their psychological well-being. However, those working under conditions of high exploitation and violence, such as street prostitutes or those held in debt bondage, face severe psychological consequences. These include post-traumatic stress disorder, depression, anxiety, and other mental health problems due to physical, sexual, and emotional violence they suffer. Debt bondage, in particular, is an extreme form of exploitation where women are kept in conditions of slavery due to unpayable debts, prevalent in underdeveloped countries. This situation subjects them to severe trauma and a constant threat of violence, exacerbating their psychological problems and making it difficult to escape this cycle of abuse and exploitation.

Street sex work, in particular, is associated with higher levels of stress and risk due to exposure to violence, third-party exploitation, and poor working conditions. Many street workers report experiences of physical and emotional abuse by both clients and pimps. This environment can lead to a higher incidence of mental health disorders, such as anxiety, depression, and post-traumatic stress disorder.

On the other hand, sex workers operating in more controlled environments, such as escort agencies or brothels, report higher levels of job satisfaction and self-esteem. These workers have more control over their working conditions, can select their clients, and generally experience less violence. This greater autonomy and control can translate into better mental health and a greater sense of empowerment.

Types of Prostitutes
Type of Prostitute Description Detailed Psychological Impacts Differences from Other Types of Prostitutes Level of Violence Clients per Day (Average)
Street Prostitute Work on the streets, earn less, and are more vulnerable High exploitation, less job satisfaction, high risk of violence Lower income, higher risk of violence and exploitation Very high 8–12
Debt-Bonded Prostitute Held in establishments under an unpayable debt, common in underdeveloped countries High exploitation, severe psychological trauma, physical and sexual violence Forced to work indefinitely, inhumane conditions Very high 10–40
Window Worker Work in brothels with windows, like in Amsterdam, earn low to moderate wages Social isolation, less job satisfaction Visible to the public, less social contact than in brothels Moderate 5–15
Bar or Casino Worker Contact clients in bars or casinos and move to another location for the service Low to moderate exploitation, potential dependence on regular clients Variable income, greater geographical mobility Moderate 3–8
Brothel Employee Work in legal brothels, must share earnings with owners Moderate exploitation, regular social contact with other workers Fixed locations, more dynamic social environment Moderate 5–10
Escort Agency Employee Work in private locations or hotels, charge high prices, must share earnings with the agency Moderate exploitation, some dependence on the agency Similar to independents, but with less control over their earnings Moderate 2–4
Independent Call Girl/Escort Work independently in hotels and homes, charge high prices and maintain privacy Less exploitation, more control over work conditions Retain all their earnings, not dependent on third parties Low 1–3

High-end prostitutes

Juliana, a high-end German prostitute

The study of the psychology of high-end prostitutes reveals a series of common patterns and traumas that shape their behavior and life choices. Many of these women come from difficult childhoods, marked by broken homes and dysfunctional family relationships, contributing to their sense of insecurity and low self-esteem. From an early age, they learn to see sex as a currency, a means to obtain the emotional contact and tangible rewards they crave.

These women, despite their superior intelligence and artistic abilities, feel emotionally adrift and lack a clear concept of their feminine role. Their adult lives are marked by a constant search for validation and security, though paradoxically, they are trapped in a profession that perpetuates their feelings of worthlessness and anxiety. Most struggle with addiction problems and unstable relationships, unable to maintain solid friendships and resorting to psychological defenses such as projection and denial to cope with their reality.

Financial success and outward luxury fail to mask their deep emotional distress. Often, they feign joy and affection toward their clients, but in their private lives, many are unable to experience sexual satisfaction and suffer from anxiety and depression. The high rates of suicide attempts among these women underscore the severity of their psychological suffering.

Psychotherapeutic treatment can offer relief and a way out of prostitution, helping these women confront and overcome their past traumas. Through therapy, some manage to establish healthier relationships and embark on new legitimate careers, finally finding a measure of stability and emotional peace.

Coping mechanisms

The White Slave, work by Abastenia St. Leger Eberle, denouncing child prostitution

"Men would ask me to urinate in bottles so they could drink it, or defecate in their mouths, or bake muffins with my feces for them to eat in front of me. One man offered me $10,000 to have sex with his dog in a film. Another was so brazen that he asked me to play the role of his nine-year-old sister, whom he used to sexually abuse as a teenager."

Andrea Heinz, former prostitute.

Female sex workers suffer intense physical, sexual, and mental abuse, widely documented in medical and public health literature. However, the mental coping mechanisms employed by these women to survive have been less studied. In the debate on prostitution, women are often divided into two groups: those who were forced into prostitution and those who 'chose' this activity. The definition of 'force' or 'coercion' can vary, but the underlying logic remains: some women are compelled to prostitute themselves through violence or economic coercion and thus deserve compassion. On the other hand, there are those who seemingly choose it freely, even though they may have other options available, such as access to social services and unemployment benefits.

The reality, however, is more complex. Women from all social classes may find themselves in prostitution due to experiences of sexual, physical, or emotional abuse and may be reenacting these traumas within the realm of prostitution. Rachel Moran argues that prostitution is not only a consequence of women's lack of economic power but exists primarily due to male demand. Prostitution is also seen as a reenactment of previous traumas. Andrea Dworkin mentioned that incest is the training ground for prostitution, indicating that experiences of childhood abuse can predispose women to prostitution. Huschke Mau adds that traumatic situations can become addictive due to the release of adrenaline, a familiar experience for those who have faced violence from a young age.

The sociologist Pierre Bourdieu suggests that the body serves as a means of memory for any social order, unconsciously internalizing the structures of social inequality or sexual hierarchies. This means that experiences of violence and degradation become integrated into one's self-perception, profoundly affecting self-esteem and self-worth. Prostituted women often internalize violence and develop dissociative mechanisms to cope with the reality of their situation. Forcing themselves to feel enjoyment during sexual acts is a common strategy to protect themselves psychologically and to meet the expectations of clients, who often need to believe that the women enjoy the sexual interaction to soothe any guilt about their actions. Prostitution also plays a role in maintaining the second-class status of all women within the gender hierarchy. Michael Meuser describes how spaces reserved exclusively for men allow them to reinforce their dominance and normalize social dynamics that perpetuate male supremacy. Therefore, the existence of prostitution has adverse effects not only on prostituted women but on all women in society.

Leaving prostitution is a long and complex process that involves not only finding a new source of income but also readjusting to daily life outside the sex trade. Women who manage to exit prostitution often face significant challenges in rebuilding their self-esteem and social integration.

Depersonalization

"To endure prostitution, you need to split your consciousness from your body, dissociate. The problem is that you can't just put them back together afterward. The body remains disconnected from your soul, from your psyche. You simply stop feeling yourself. It took me several years to learn that what I sometimes feel is hunger and that it means I need to eat something. Or that there is a sensation indicating that I am cold and need to put on some clothes."

Huschke Mau, survivor, after being a prostitute for 10 years.

"Even when I tried to dissociate during those countless paid rapes, I found it difficult to separate what was happening to my body from my real self."

Geneviève Gilbert, Canadian prostitute.

Prostitutes have a high level of dissociation, such as not recognizing themselves in a situation, forgetting unpleasant events, or refusing to perceive certain aversive events that affect them.

Dissociation is a psychological process in which a person disconnects from their thoughts, feelings, memories, or identity. This phenomenon is especially prevalent in individuals who have experienced severe traumas, such as childhood sexual abuse. Dissociation can manifest in various ways, from amnesia to the creation of multiple identities, known as multiple personality disorder (MPD).

Dissociative identity disorder (DID), formerly known as Multiple Personality Disorder, is a condition often misunderstood and sensationalized in the media. However, various studies have revealed that between 1 and 3% of the general population meet the diagnostic criteria for DID.

Various studies have investigated the relationship between child sexual abuse and dissociative disorders. The disorder most commonly associated with childhood sexual abuse is multiple personality disorder. In a study by Colin A. Ross and colleagues, 236 people with MPD were examined, and a high prevalence of childhood sexual abuse and dissociation was found. This study also highlighted that, in addition to MPD, prostitution and work in the adult entertainment industry (exotic dancers) showed a significant incidence of dissociative experiences.

To assess the prevalence of dissociation and childhood sexual abuse, tools such as the Dissociative Disorders Interview Schedule (DDIS) and the Dissociative Experiences Scale (DES) were used. These instruments help identify and measure the frequency and severity of dissociative symptoms. In the mentioned study, 60 subjects were included, divided into three groups: 20 patients diagnosed with MPD, 20 sex workers (prostitutes), and 20 exotic dancers. The results showed that most subjects with MPD met the DSM-III-R criteria for the diagnosis of this disorder, and dissociation was common in all three categories of subjects studied.

Causes

One of the most common causes of DID is childhood sexual abuse. When a child experiences a stressful event such as sexual abuse, the fight or flight response is activated. Dissociation is a form of psychological escape when the child cannot physically escape. The child may imagine that the abuse is happening to another person or another "part" of themselves. If the abuse is severe and prolonged, this "part" can develop its own identity, separate from the child's conscious memory.

Survivors of trauma may exhibit symptoms instead of memories. Many people with DID report memories of childhood traumas and evident symptoms such as "waking up" in unfamiliar places or meeting people who call them by another name. However, it is common for some individuals not to remember their childhood traumas, but to exhibit more subtle and difficult-to-recognize symptoms of PTSD and DID. These symptoms include inexplicable feelings of guilt, shame, and worthlessness, emotional numbness, concentration problems, thought insertion, Depersonalization and Derealization. Without known traumatic memories to attribute these symptoms to, the person is often misdiagnosed and only superficial problems are treated, masking their true needs.

Many trafficking victims have histories of child sexual abuse, a primary cause of PTSD and DID. Additionally, studies have shown that women in prostitution experience PTSD levels comparable to those of combat veterans. It has also been found that 35% of prostituted individuals and 80% of exotic dancers experience dissociative disorders, and between 5% and 18% of prostituted individuals and 35% of exotic dancers meet the diagnostic criteria for DID.

Religion

"Our work is quite terrible, isn't it? [...] now only death, because leaving this only after God takes us away... dealing with strange men touching your body... It's horrible, like being in an anthill, it's scary, in my opinion, being in an anthill, someone touching you and you don't like that man... God forbid. Because entering this boat, it seems like an entity, a thing... Can you imagine? Being a normal person, and one comes, another comes and you have to do the job... You're there only for the money, you don't enjoy it or anything. We become cold people, I don't know, I think it's a demonic thing, but we cling to God and move on... It's dangerous work... And dirty."

Lara, 44 years old, has worked as a prostitute for over 20 years in Salvador, Bahia.

Women in prostitution often turn to different religious traditions to address their situation, though with very different approaches. For some, religion presents an escape route, offering spiritual redemption and a fresh start. Some Pentecostal churches in Brazil have provided emotional and community support, encouraging women to leave prostitution through conversion, abandoning sinful behaviors, and integrating into a community that values their new moral identity.

In contrast, Afro-Brazilian religions such as Umbanda and Candomblé provide tools to improve their economic success within prostitution. Through rituals and offerings to entities like Pombagira, these women seek to attract more clients and increase their income. These practices reflect a pragmatic and materialistic relationship with the divine, based on the belief that spiritual entities can grant favors and material success in exchange for specific offerings.

Umbanda

Erika Bourguignon explored dissociative phenomena in different cultural contexts. In her research, Bourguignon compared dissociative cases, such as a woman in New York and a man in São Paulo, showing how dissociation manifests in culturally specific ways. In the context of Umbanda, an Afro-Brazilian religion, dissociative states are interpreted as spiritual possession, where the individual acts as a medium for ancestral spirits. These experiences are not seen as pathologies but as mediumistic abilities that require development and acceptance within the religious community. For prostitutes, dissociation can be a necessary strategy to manage the dissonance between their personal identity and the demands of their work. This mental separation allows them to perform sexual acts without involving their true selves, creating a psychological barrier that protects their mental health. These dissociative experiences enable the individual to face stressful situations without being completely overwhelmed by them.

Bernstein and Putnam propose a continuum for dissociation in the psychopathological dimension, suggesting that not all dissociative experiences are inherently pathological. This perspective is useful for understanding how prostitutes use dissociation as a tool to survive emotionally and psychologically in a hostile environment. In practice, prostitutes may experience a variety of dissociative states, from feeling like external observers of their own bodies to adopting alternative identities that handle interactions with clients. These identities can act as a form of self-protection, allowing women to fulfill their work without feeling the direct emotional impact.

Pombagira

In Brazil, many women in prostitution turn to spiritual and mystical practices to increase their income. These women frequent spiritist houses and candomblé or umbanda terreiros, where they are advised to buy herbs for baths and products for offerings to spiritual entities like the Lady of the Night or Pombagira. The belief is that these rituals will attract more clients and, therefore, generate higher income. For each entity, the offerings vary and include drinks, perfumes, and red objects. Although some women express skepticism towards these beliefs, many attribute financial success to their participation in these rituals. It is noted that older women often have more economic success than their younger counterparts, attributed to their involvement in these spiritual practices.

The cost of these rituals can be significant. Some women report spending large sums of money on products for offerings, with the promise of obtaining greater profits. However, there is a mixed perception of the effectiveness of these rituals, as although they may attract more clients, the associated cost of offerings may not be compensatory.

Pombagira is a central figure in these spiritual practices, seen as a powerful entity capable of performing "miracles" and attracting success in love, relationships, and material progress. This entity is associated with manipulating sensuality and sexuality and is believed to remove obstacles and enemies to ensure the success of her devotees. The beliefs surrounding Pombagira are not limited to prostitution. In the Brazilian social imagination, Pombagira represents the archetype of the ritual prostitute and is commonly requested to perform works on romantic relationships. Although not all Pombagiras are considered prostitutes, the connection with prostitution is due to her representation as a free and powerful woman. Women in prostitution who participate in these spiritual practices do so under the principle of reciprocity. They offer objects and perform rituals in exchange for economic favors and success in their profession. This system of exchange reflects similar practices in popular Catholicism, where people make promises to saints in exchange for divine favors. However, in prostitution, these offerings are primarily aimed at improving sexual attraction and financial success.

The article "A Pomba-Gira in the Imagination of Prostitutes," published in the journal "Man, Time, and Space," examines the relationship between prostitutes and Pomba-Gira, an entity from the Umbanda pantheon known for her free manifestation of female genital power. This study, conducted by Francisco Gleidson Vieira dos Santos and Simone Simões Ferreira Soares, delves into the symbolic and psychological importance of Pomba-Gira in the lives of prostitutes. Pomba-Gira represents a powerful archetype in Umbanda, characterized by attributes associated with sexuality, disobedience, and the transgression of social norms. From a deep psychological perspective, this entity can be interpreted as a projection of the collective unconscious of prostitutes, who find in her a figure of empowerment and resistance. Identifying with Pomba-Gira allows prostitutes to negotiate their self-esteem and sense of agency in a social context that stigmatizes and marginalizes them.

In psychological terms, the figure of Pomba-Gira could be seen as a manifestation of a dissociative personality in prostitutes, emerging as a defense mechanism against the adversity of their environment. Dissociation is a psychological process by which a person can divide their identity into different states or personalities to face difficult or traumatic situations. In this case, Pomba-Gira would serve as an alternative personality, allowing prostitutes to perform their work more bearably and with less emotional pain. Pomba-Gira, with her defiant character and celebration of free sexuality, offers an alternative narrative to the guilt and shame commonly associated with prostitution. This identification with a powerful and transgressive entity can help prostitutes reconnect with repressed aspects of their identity and find a sense of dignity and worth in a sacred context. By incorporating Pomba-Gira during rituals, prostitutes can experience a form of catharsis, temporarily freeing themselves from the emotional burdens of their daily reality.

Monique Augras, cited in the study, suggests that Pomba-Gira is a Brazilian creation that emerged from the destitution of the sexual characteristics of Iemanjá, another Umbanda figure syncretized with the Immaculate Conception. This new entity channels the most scandalous aspects of female sexuality, directly confronting patriarchal values. From a Jungian point of view, Pomba-Gira could be seen as a manifestation of the anima, representing the erotic and autonomous dimension of the female unconscious that challenges the restrictions imposed by patriarchal society. Interviews with "fathers-of-saint" and other Umbanda practitioners reveal that Pombas-Giras are considered complex and powerful figures, revered for their ability to influence matters of love and desire. This reverence is reflected in ritual practices, where Pombas-Giras, when incorporated by mediums, act as agents of transformation and empowerment. This allows prostitutes to assert their value and dignity in a sacred context.

Positive identity

"I am of the opinion that no woman, except those who are placed when they are minors to be exploited, becomes a sex worker without her consent. I am totally against that kind of discourse that says we need someone to get us off this path."

Claudia de Marchi, 36, luxury escort and former lawyer

One of the fundamental principles of social identity theory is that individuals seek to enhance their self-esteem through their social identities, and an important component of self-definition is occupational identity. Individuals employed as prostitutes constantly engage in various ideological techniques to neutralize the negative connotations associated with the work they do. Ashforth and Kreiner identified three of these techniques: restructuring, recalibration, and refocusing, which are used at the group level to transform the meaning of stigmatized work. Restructuring allows prostitutes to transform stigma into a symbol of honor by asserting that they provide an educational and therapeutic service rather than selling their bodies.

These protective techniques enhance the self-definition of prostitutes and can be considered coping mechanisms. However, engaging in these techniques requires mental and emotional energy, which can become a stressor. Additionally, the requirement for a strong group culture to support these ideological techniques is not always present for prostitutes. Even with efforts to adopt these techniques, most members of occupations considered "dirty work" maintain some ambivalence about their jobs, as they remain part of a broader society that stigmatizes their labor as "dirty" and have continuous contact with people outside their occupation. Prostitutes also have to construct their self-identity in circumstances that put pressure on the relationship between their professional and personal lives. The bodies of prostitutes, and potentially their psyches, are consumed by the client in the act of commercial sex, creating additional pressure to maintain a division between the professional and the personal. Many of the techniques that prostitutes use to maintain this division are considered coping mechanisms.

Emotional labor in prostitution

Emotional labor is defined as the "act of displaying organizationally desired emotions during service transactions." Emotional labor is believed to be more prevalent in service occupations, as people working in services are generally subject to stricter norms about the appropriate expression of emotions in certain situations. In particular, what is disturbing for people is the imbalance or dissonance between what the worker feels and the emotions they must display. This discrepancy between felt and expressed emotions has a negative effect on physical health.

Prostitutes face very different demands compared to the general population regarding the emotional labor required. Their work consists of acts that are intensely personal and intimate. They must fake affection and emotion to develop a regular clientele. One way that prostitutes cope with the emotional demands imposed on them is by "categorizing different types of sexual encounters [as] relational, professional, or recreational." This way, they can maintain distance from the encounter with the client and preserve their self-identity. The literature also suggests that prostitutes maintain emotional distance by using condoms at work or during professional sex and by refusing to kiss clients. Kissing "is rejected because it is too similar to the kind of behavior one would engage in with a non-commercial partner; it implies too much genuine desire and love for the other person."

Use of stimulation and pleasure

Pleasure and pain are more related than they seem. Under certain circumstances, pain can intensify sensations of pleasure due to the release of endorphins and other chemicals in the brain. This mechanism is similar to the "runner's high" that athletes experience after an intense exercise session. The relationship between pleasure and pain in the human brain is intricate. They share similar neuronal pathways, allowing the brain to modulate pleasurable experiences to counteract pain. This neurochemical capability can explain how some sex workers find pleasure in their interactions, using it as a way to dissociate from the physical and emotional pain that often accompanies their work. The release of neurotransmitters such as endorphins during these moments can provide temporary relief and a sense of well-being.

Prostitution involves practices aimed at minimizing physical issues, although these same practices can generate psychological complications. Sex workers use stimulation and pleasure to reduce physical pain, which, paradoxically, can lead to significant emotional disconnection.

Some clients seek not only to receive pleasure but also to provide pleasure to the worker. For example, a client may pay to give a massage and provide sexual pleasure, which can result in a gratifying experience for both. This type of interaction can go beyond the negative stereotypes associated with sex work, showing that it does not always involve exploitation or abuse. A study by Elizabeth Megan Smith of La Trobe University, published in the journal Sexualities, investigated how sex workers integrate pleasure into their work. This study, titled "'It gets very intimate for me': Discursive boundaries of pleasure and performance in sex work," involved nine women from the sex industry in Victoria, Australia. Through narratives and photographs, the participants explored their relationship with intimacy, performance, and pleasure. The study shows that sex workers often experience pleasure during their work to achieve better vaginal lubrication, reducing the risk of tears and other physical injuries. However, this pursuit of pleasure is not inherently positive.

Some sex workers emphasize the importance of focusing on their own pleasure to maintain a sexual experience and avoid resentment towards clients and the work itself. The ability to reach orgasm can be a strategy to preserve personal integrity. For many, forcing oneself to feel pleasure in unwanted situations can be a survival strategy to avoid physical pain but comes at a high psychological cost. Sex workers may experience a diminished ability to form genuine emotional connections outside of work, leading to feelings of isolation and difficulties in their personal relationships.

Stockholm syndrome

Stockholm syndrome, a phenomenon where victims develop bonds with their captors as a survival strategy, has been mentioned in the media in relation to this vulnerable population, but it has not been formally investigated. The four main criteria of Stockholm syndrome (perceived threat to survival, displays of kindness by the captor, isolation from other perspectives, perception of inability to escape) have been identified in the narrative accounts of these women.

The threat can be explicit, like physical violence, or more subtle, like emotional abuse or the threat of harm. Victims may believe they cannot survive without the abuser's protection and support and may feel responsible for the safety of others, such as their families. The perception of kindness, even in the smallest form, can be disproportionate due to the victim's low self-esteem. These victims may interpret any cessation of violence or minimal gesture as an act of kindness and may downplay their situation with thoughts like "at least he didn't..." or "it could have been worse".

The first criterion of Stockholm syndrome is the perception of a threat to survival and the belief that the captor would carry out that threat. Many trafficked women experience physical violence and torture, perpetrated by brothel workers (pimps, traffickers, madams) as well as clients. The second condition is the captor's display of love or kindness. Many women maintain relationships with their traffickers or develop bonds with clients, often hoping to start a family with them. This "act of kindness" can be any action that helps the woman survive, as her survival is essential for the functioning of the sex market. The third condition is isolation from the outside world. Many women described their first months in the brothel as completely isolated, contributing to Depersonalization and demoralization. The fourth condition is the perception of inability to escape. Sex workers who attempted to escape were publicly beaten to deter others from trying.

Rescued sex workers refuse to testify against their traffickers, a behavior observed in countries like the United States, England, and India. The closest psychiatric diagnoses to the traumas suffered by these women are complex post-traumatic stress disorder (CPTSD) and disorders of extreme stress not otherwise specified (DESNOS), but these are not included in the DSM IV due to debates about their distinction from post-traumatic stress disorder (PTSD). Stockholm syndrome could be an additional explanation for this behavior, as the conditions described for this syndrome are present in the accounts of sex workers.

Addictions

The relationship between prostitution and addiction is a complex phenomenon involving multiple psychological, social, and economic factors. Many individuals involved in prostitution may have experienced significant traumas in their lives, such as physical, emotional, or sexual abuse during childhood. These traumas often contribute to mental health issues like post-traumatic stress disorder (PTSD), depression, and anxiety, which can predispose a person to develop addictions as a coping mechanism. Individuals involved in prostitution and struggling with addictions often experience a range of negative psychological effects. Shame, guilt, and low self-esteem are common, exacerbated by social stigma and negative self-perception. Addiction, in turn, can lead to further social alienation and isolation, reinforcing these negative feelings and contributing to the persistence of addictive behavior.

Emotional and sexual addiction

"When it's a handsome man and he does it well, I win. I feel desired, satisfied, and I also earn money for feeling pleasure. Is there anything better?... Some pay me just to cry, vent, and receive affection. Some nights, I play the role of a psychologist."

Lorena, 23 years old, has been prostituting for seven months and has already been a victim of rape.

Involvement in prostitution is not always driven solely by economic reasons. Psychological and emotional factors play a significant role. Some individuals in sex work may experience addictions related to seeking validation, the need to control trauma, or as a way to cope with stress and anxiety. Childhood trauma and prolonged stress can alter brain responses, increasing susceptibility to addictive behaviors, not necessarily related to substances but to activities that generate a sense of reward, such as commercial sex. Some women in prostitution find this activity a way to exert power and control, especially if they have suffered traumas or seek to regain a sense of agency in their lives. This control can be a way to manage their self-esteem and feel validated through men's attention and desire. Additionally, some seek prostitution as a form of emotional independence and autonomy from adverse personal situations.

Some studies highlight that not all individuals in sex work are there due to extreme economic need; some choose this profession for the exploration of their sexuality and the financial independence it offers. For some, prostitution offers a temporary escape from personal problems and a sense of empowerment, despite significant risks to their physical and emotional well-being.

"There will be a woman whose dream and pleasure is this, to have everything she finds here. Everything. Even the fights, the confusions attract to tell the truth, even the problems, what you have in the area, sometimes, when you leave, you miss it."

This addiction is not always driven solely by the desire for money but also by the need for validation and power over their clients. Compulsive sexual behavior can cause changes in brain circuits, leading individuals to seek more intense sexual encounters to achieve the same satisfaction, similar to other addictions such as drugs or alcohol. Additionally, prostitutes can be influenced and develop addictive behaviors due to constant interaction with clients who have sexual addictions. Repeated exposure to these compulsive behaviors can contribute to sex workers developing similar addictions, either seeking emotional validation or feeling a compulsive need to engage in sexual activities to gain a sense of control and power. Besides sex and the need for validation, prostitutes can also develop addictions to behaviors such as gambling, compulsive shopping, excessive exercise, and social media use. These behavioral addictions are similar to substance addictions in how they affect the brain and can lead to financial, health, and personal relationship problems. However, prostitution is rarely a completely free choice when options are limited, and socio-economic conditions are adverse.

Addiction to cosmetic surgeries

Sex workers often resort to cosmetic procedures to enhance their appearance, hoping to increase their attractiveness and, consequently, their income. This trend is especially notable in countries like Colombia, where the cosmetic surgery industry is booming.

Prostitutes may undergo multiple surgeries to achieve an ideal of beauty influenced by cultural norms and client demands. This pursuit of physical perfection can become an addiction similar to other behavioral addictions, where individuals continuously seek surgical procedures despite potential negative risks. This addictive behavior is often related to psychological disorders such as body dysmorphic disorder (BDD), a mental condition where individuals are excessively concerned about perceived defects in their appearance.

Substance abuse

"At some point, I also got hooked on sleeping pills, very common among us, prostituted women who are anxious and unable to disconnect at night."

Geneviève Gilbert, Canadian prostitute.

People engaged in prostitution are predominantly women, although men are also involved. There are various types of prostitution, from high-end escort services to street-level services. In the United States, prostitution is illegal except in some counties in Nevada. Women in street prostitution often face greater social and legal consequences, including high rates of arrest, incarceration, violence, and victimization, as well as health, mental health, and substance abuse issues.

"I dressed very provocatively when I was nine or ten years old, started experimenting with chemical drugs at 13, and lost my virginity just after turning fourteen to an older boy who pressured me until I finally gave in. From age 16, I spent three years dating a crack dealer who emotionally abused me with belittling and controlling tactics. He then cheated on me, gave me chlamydia, and eventually started physically abusing me."

Andrea Heinz, former prostitute.

Substance abuse is common among women in prostitution, including the use of heroin, cocaine, marijuana, and alcohol. Some women start prostituting to fund their drug use, while others develop substance abuse problems after becoming involved in prostitution. Substance use can provide women with a coping mechanism for the difficulties of prostitution. Most women in prostitution have experienced violent events throughout their lives, often from childhood. There is a high prevalence of childhood sexual abuse among women in prostitution, and many also face violence in their intimate relationships and within the context of prostitution. These experiences of violence and trauma throughout life place women at risk of developing disorders such as post-traumatic stress disorder (PTSD), anxiety, depression, and other related issues.

The high levels of substance abuse and trauma among women in prostitution suggest the need for programs that address both issues comprehensively. This study aims to inform the implementation of the SPD and highlight the importance of developing and implementing effective interventions for this population.

Recidivism

For some, dissatisfaction and increasing emotional distress prompted periods of disengagement from sex work, ranging from days to years, or the beginning of what they described as their exit from sex work. However, for most, these breaks were short-lived, and emotional and financial difficulties led them back. Emotional and financial difficulties were frequently interconnected, as drug addiction as a means of emotional management created economic problems. Participants struggled with limited monetary benefits and faced significant barriers to accessing alternative employment and educational opportunities. Women reported few options for earning quick money, making them return to sex work as an immediate solution to urgent financial needs. Despite not necessarily wanting to return, sex work was seen as an easy way out in situations of extreme economic need. Even those who tried to leave sex work found it difficult to refuse face-to-face propositions or calls from regular clients. Once experienced in sex work, alternative options seemed scarce, and sex work offered a level of familiarity and flexibility. Additionally, for some, it was important to avoid the time restrictions and obligations associated with formal employment, preferring to avoid the legal implications of criminal activities such as theft. Substance use often drove the need to earn quick money with few obligations, although some women described how sex work met basic needs and then became accustomed to the extra money. In addition to financial appeal, some participants were drawn back to sex work seeking companionship, purpose, and relief from loneliness and boredom. Returning to sex work offered a sense of belonging, especially for those with limited family contacts or loss of custody of their children due to drug problems. Although some women accessed activities in support services, they reported a limited range of self-directed leisure activities, sometimes leading them back to sex work due to boredom.

Psychological consequences

Post-traumatic stress disorder

Using fMRI, this image investigates whether post-traumatic stress disorder (PTSD) affects the ratio of gray matter to white matter in women with borderline personality disorder. These techniques help identify regions responsible for psychiatric disorders and assess how different activities affect brain function.

One of the strongest psychological effects of prostitution on sex workers is post-traumatic stress disorder (PTSD). PTSD is described as episodes of anxiety, depression, insomnia, irritability, recurrent memories, emotional numbness, and hypervigilance. PTSD symptoms are more severe and long-lasting when the stressor is a person. According to Melissa Farley, "PTSD is normative among prostituted women." In San Francisco, Farley conducted a study with 130 prostitutes, 55% of whom reported being sexually assaulted in childhood and 49% reported being physically assaulted in childhood. As adults in prostitution: 82% had been physically assaulted, 83% had been threatened with a weapon, 68% had been raped while working as prostitutes, and 84% reported being homeless at some point. According to the 130 people interviewed, 68% met the DSM III-R criteria for a PTSD diagnosis. Farley notes that 73% of the 473 people interviewed in five different countries (South Africa, Thailand, Turkey, US, and Zambia) reported being assaulted in prostitution and 62% had been raped in prostitution. Any prostitute who experiences trauma can develop PTSD. Research found that of the 500 prostitutes interviewed worldwide, 67% suffer from PTSD.

I have experienced horrible, disgusting, and traumatizing things that no person should ever endure. I have had men force me to perform sexual acts... They violently sodomized me, strangled me, photographed and filmed me having sex without my knowledge or consent, and some men used me so forcefully that my genitals and anus were torn and bleeding. I have had men so obsessed that they contacted me hundreds of times a day, followed me home, and randomly showed up knocking on my door in the middle of the night. I have been raped numerous times without a condom.

— Andrea Heinz, former prostitute.

The study titled "Prostitution in Five Countries: Violence and Post-Traumatic Stress Disorder" conducted by Melissa Farley, Isin Baral, Merab Kiremire, and Ufuk Sezgin and published in Feminism & Psychology in 1998 investigates the prevalence of violence and post-traumatic stress disorder (PTSD) among prostituted individuals in South Africa, Thailand, Turkey, the United States, and Zambia. The research, based on interviews with 475 individuals in prostitution, shows that 73% of respondents reported being physically assaulted, 62% reported being raped, and 67% met the diagnostic criteria for PTSD. The study also examines differences in experiences of violence by location of prostitution (street or brothel) and race, although it found no significant variations in the severity of PTSD among different groups. The data indicate that prostitution inherently carries a high risk of violence and psychological trauma, regardless of the cultural or legal context. Additionally, an average of 92% of respondents expressed a desire to leave prostitution, needing support such as job training, healthcare, and physical protection. The research demonstrates that prostitution is a form of violence against women and raises serious implications for public policies and support programs aimed at individuals in prostitution.

The table provides a detailed comparison between sex workers with current PTSD and those without current PTSD, focusing on several key dimensions: demographics, drug use, risky sexual behaviors, and mental health and trauma experiences.

In terms of demographics, the mean age of women with current PTSD is 34 years, similar to women without current PTSD, who have a mean age of 33 years. Both cohorts have a median of 9 years of schooling. However, a notable difference is the rate of homelessness in the past 12 months, which is 50% among women with current PTSD, compared to 42% in women without current PTSD. Additionally, A&TSI (Aboriginal and Torres Strait Islander) status is more prevalent among women with current PTSD (27% vs. 20%).

Regarding recreational drug use, the median age at first use of injectable drugs is slightly lower in women with current PTSD (17 years) compared to those without current PTSD (18 years). The rates of heroin dependence are high in both cohorts, though slightly lower in women with current PTSD (73% vs. 86%). Dependence on cocaine and cannabis is also relevant, with similar percentages between both groups. However, a significant finding is that 20% of women with current PTSD shared injection equipment in the last month, compared to 40% of those without current PTSD, suggesting possible differences in risk behaviors related to drug use.

In terms of risky sexual behaviors, the median age at starting sex work is slightly higher in women with current PTSD (20 years) compared to those without current PTSD (18 years). The prevalence of condom use is high in both groups, both during sex with clients (91% for current PTSD and 83% for no current PTSD) and during oral sex with clients (62% for current PTSD and 60% for no current PTSD). This indicates a high level of awareness about protection in both groups.

The most pronounced differences are observed in variables related to mental health and trauma. Women with current PTSD report a significantly higher median number of traumas (7 traumas) compared to those without current PTSD (5 traumas). Severe depressive symptoms are more common in women with current PTSD (73% vs. 48%), as are suicide attempts (50% vs. 40%). Both groups have similar rates of physical assault while working (77% in both cases) and childhood sexual abuse (82% in current PTSD vs. 72% in no current PTSD). However, childhood neglect is significantly more reported by women with current PTSD (59% vs. 28%), and adult sexual assault is also notably higher in this group (82% vs. 53%). The median age at first sexual assault is slightly lower in the group with current PTSD (13 years) compared to the group without current PTSD (14 years).

Analysis

This analysis suggests that sex workers with current PTSD not only face a higher burden of trauma and adverse conditions throughout their lives but also exhibit more severe patterns of risky behavior and mental health consequences. The high prevalence of multiple traumas, severe depression, and experiences of violence in both childhood and adulthood demonstrates the need for targeted interventions and trauma-focused treatments for this vulnerable group. The lower rate of sharing injection equipment among the group with current PTSD could indicate greater caution in certain health risk aspects, but this does not mitigate the need for comprehensive support due to the severity of mental health issues and traumatic experiences they face.

Symptoms

The study conducted by Young-Eun Jung and colleagues compared mental symptoms, especially PTSD symptoms, in women who escaped prostitution, activists helping in shelters, and a control group. The research evaluated 113 ex-prostitutes living in shelters, 81 activists, and 65 control subjects using self-report questionnaires on demographic data, trauma-related symptoms and PTSD, stress reactions, and other mental health factors. The results showed that ex-prostitutes exhibited more frequent and severe responses to stress, somatization, depression, fatigue, frustration, sleep problems, smoking, and alcoholism, as well as more frequent and severe PTSD symptoms compared to the other two groups. Activists also showed higher tension, sleep problems, smoking, and more frequent and severe PTSD symptoms than the control group. These findings suggest that involvement in prostitution may increase the risks of exposure to violence, psychologically traumatizing not only the prostitutes themselves but also those who help them. Moreover, the effects of trauma can persist for a long time. Future research is needed to develop methods to assess specific factors contributing to vicarious trauma in prostitution and to protect field workers from this trauma.

Borderline personality disorder

Borderline personality disorder (BPD) is a mental disorder characterized by significant impulsivity, seduction, and excessive sexuality. Sexual promiscuity, sexual obsessions, and hypersexuality or sexual addiction are common in both men and women with BPD. Research indicates that more than 90% of sex addicts exhibit personality disorder traits and often suffer from other psychological issues. BPD is one of the most prevalent personality disorders among those with hypersexuality. A person with BPD may engage in impulsive and self-destructive behaviors, including sexual activity as a form of self-harm. In this context, many individuals with BPD and hypersexual behaviors may be drawn to prostitution as a way to meet their emotional and psychological needs. Prostitution may be seen as an outlet for impulsivity and the need for emotional validation, offering a sense of control and worth that individuals with BPD may desperately seek. Additionally, the financial instability often associated with BPD may drive these individuals to prostitution as a means of economic support. Participation in prostitution can, in turn, exacerbate BPD symptoms due to exposure to abuse, violence, and social stigma, creating a harmful cycle that further hinders treatment and recovery. Jane Eloy, a sex worker, provides a raw perspective on how the search for validation and instant gratification can be driven by emotional deficiencies and a need for recognition. From a psychological standpoint, the behavior of participants shows power dynamics and cognitive dissonance, where unmet expectations generate tension that is resolved by conforming to group rules. This allows for the exploration of repressed sexual identities and power roles, using transgression and control as means to fulfill subconscious desires and resolve deep-seated insecurities.

I had a sexual encounter with him and he ejaculated in five minutes. I was frustrated because I wanted to have an orgasm with him. I went upstairs to play a card game with friends at Paul's house. The winner would win money, and the loser would have to perform a punishment. The punishment would be that the man ejaculates, and the woman would have to do a striptease or live sex. I lost and had to have sex in front of everyone, while the others participated in the game and chose the positions. "Put her on all fours, touch her clitoris." My luck was that the man in question was a beautiful 1.85m tall black man with a huge and wonderful penis. I was happy because I managed to have an orgasm.

The prevalence of survival sex and mental illnesses are overrepresented in homeless populations. A recent study evaluated the relationship between borderline personality disorder (BPD) symptoms and participation in survival sex among homeless women. Researchers surveyed 158 homeless women about self-reported BPD symptomatology and sexual history. Bivariate and multivariate analyses in this study revealed that certain BPD symptoms are strongly correlated with survival sex among adult homeless women. The results indicate that impulsivity is a significant factor associated with participation in survival sex, even after controlling for other demographic and homelessness experience variables. These findings suggest the need for service agencies and others working with at-risk female populations to consider impulsivity as a critical factor when developing interventions to prevent survival sex. The study sample included women from Omaha, Nebraska; Pittsburgh, Pennsylvania; and Portland, Oregon, and interviews were conducted in shelters, community meal programs, and outdoor locations. Participants received $20 for completing the interviews. The results showed that 23.8% of the women surveyed had engaged in survival sex, and BPD dimensions such as impulsivity and fear of abandonment were significantly related to this practice. Age was also identified as a risk factor, with a higher likelihood of engaging in survival sex as women aged. The results highlight the need for training for service providers working with homeless populations, particularly to identify and support older women with high levels of impulsivity. This study underscores the importance of continuing to investigate the relationship between BPD and survival sex to develop more effective interventions.

Self-destructive behaviors

Self-destructive behavior in female sex workers refers to actions that endanger their own safety and physical health, considered a form of self-destruction. This phenomenon manifests through high levels of suicidal ideation and suicide attempts, primarily motivated by emotions such as shame, anger, and resentment. Among sex workers, it is common to find underdeveloped psychological protection mechanisms, contributing to maintaining risky sexual behaviors. These mechanisms include primitive forms of psychological defense, such as denial and projection. Additionally, there is a significant propensity toward active victim behaviors, characterized by a tendency to take risks and adopt a passive or provocative attitude in dangerous situations.

The analysis of the psychological and behavioral patterns of these women has identified three main variants: the emotional-anxious-dysthymic, the exalted affective-hyperthymic-cyclothymic, and the demonstrative-excitative-stubborn. The first is characterized by high emotional lability, a pessimistic perception of reality, and low self-esteem. The second variant shows turbulent behavior with unstable emotional responses and a constant search for entertainment and pleasure. The third variant is distinguished by egocentrism, irritability, and a tendency towards conflict due to a lack of acceptance of other opinions.

In terms of general and sexual education, it has been found that many sex workers lack adequate training, contributing to a disharmonious personality and a lack of adaptability. This educational deficit includes both the absence of sex education in the family environment and exposure to immoral or repressive types of education.

Women who engage in prostitution on the street face numerous problems that can increase their risk of having suicidal thoughts. Factors such as violence, substance abuse, mental health issues, and lack of social support are common in their lives and significantly contribute to this risk. Street prostitutes often live in difficult and dangerous conditions. Many have been victims of physical, emotional, or sexual violence. A study conducted in several European cities revealed that approximately 60% of street prostitutes have experienced some form of violence in the past year, and 42% report having had suicidal thoughts during the same period. Additionally, it was found that 35% of these women suffer from clinical depression, and 25% have attempted suicide at least once in their lives.

A study conducted by Alexandre Teixeira from the Faculty of Psychology at the University of Porto concluded that 44% of women who engage in street prostitution have had at least one suicidal episode, identifying precariousness, lack of legislation, and exposure to violence as the main risk factors. The research, which included 52 street prostitutes aged 18 to 60, revealed that the lack of income is the primary reason why these women turn to prostitution, although they recognize that this activity is insufficient for their sustenance. Teixeira noted that 23 of the women studied had attempted suicide one or more times, attributing this high rate of suicide attempts to causes such as victimization and exposure to verbal, physical, and sexual violence from clients and peers. He also highlighted that legal regulation of prostitution, with rights to social protection and the possibility of making contributions to social security, could positively influence these women's emotional health. According to the researcher, approximately 70% of the participants have been in prostitution for five or more years, which allows it to be considered a career rather than a temporary activity, although the women themselves do not usually perceive it this way, referring to prostitution as a temporary solution to immediate problems.

Self-harm and suicide

The diathesis-stress theory of suicide suggests that a biological predisposition (diathesis) combined with negative life circumstances (stress) precipitates suicidal behaviors. Women engaged in sex work and who use drugs face multiple risk factors for suicidal ideation and attempts, including childhood adversities, high levels of physical and sexual violence, and social stigmatization. Violence and substance use can have an interdependent relationship, where intimate partner violence can increase alcohol and drug consumption, and vice versa. Stigma and discrimination, especially related to sex work and drug use, increase the risk of suicide by generating social isolation and feelings of internal shame.

The study "Increased burden of suicidality among young street-involved sex workers who use drugs in Vancouver, Canada" investigated the risk of suicide attempts among young people living on the street and engaged in sex work in Vancouver, Canada. Data were obtained from the At-Risk Youth Study, a prospective cohort of street youth who use drugs. Multivariable generalized estimating equation analyses were used to determine if these youth had an elevated risk of attempting suicide, controlling for possible confounding factors. Between September 2005 and May 2015, 1210 youth were recruited, of whom 173 (14.3%) reported having recently attempted suicide. In the multivariable analysis, youth engaged in sex work were more likely to report recent suicide attempts. Systematic discrimination and unaddressed trauma were found to contribute to the increased risk of suicide in this population.

Anna's suicide and prostitution in London

In 2009, a Chinese woman named Anna committed suicide near Heathrow Airport in London. Friends later discovered that she worked as a prostitute in an illegal massage parlor. Jenny Lu, an art student from Taiwan and Anna's friend, investigated her friend's secret life, resulting in her first feature film, "The Receptionist." The film, which premiered in Taiwan in 2017, has yet to have a release date in Brazil. Anna, originally from a small town in China, moved to London in search of a better life but ended up leading a double life unknown to those close to her. Lu contacted women who worked with Anna at the massage parlor, discovering that many were immigrants from China, Malaysia, the Philippines, and Thailand, some with false passports or through arranged marriages. Anna, married to an unemployed Briton, worked to pay off the debt from her fake marriage and help her brother in China. Lu's film portrays the mistreatment and abuse these women face, including extortion and violence from criminals offering "protection." Despite the fictional nature of the scenes, they are based on the real experiences of Anna and her colleagues. Lu arranged meetings between the actors and the women to ensure the script's authenticity. Many of these women continue in prostitution due to language barriers and the difficulty of finding well-paying jobs. The film highlights how these women live in isolation, fearing discovery by their neighbors and working with the curtains always closed. Anna, 35, had been in the sex industry for only a year when she committed suicide. Family pressure and the shame of her secret work contributed to her decision. Lu's film, partially funded by Taiwanese agencies and crowdfunding, was selected for the Edinburgh film festival and received nominations in Italy and Taiwan.

Depression

Sorrow, by Vincent van Gogh

A study conducted by researchers at the Pontifical Catholic University of Rio Grande do Sul (PUC-RS) revealed that 67% of prostitutes in Porto Alegre exhibit symptoms of depression. Published in the Revista de Psiquiatria do Rio Grande do Sul, the study evaluated 97 women aged 18 to 60 who engage in prostitution in various settings, such as bars, nightclubs, and streets. The research analyzed variables such as age, educational level, religious practice, skin color, reasons for continuing the activity, average monthly income, intention to leave prostitution, condom use, sexually transmitted diseases, and illicit drug use. To assess depressive symptoms, a 21-question questionnaire about the previous week was used. Despite the participants' average monthly income of approximately one thousand reais, a relatively high figure compared to the average Brazilian salary, more than 90% continued in prostitution for economic reasons, and 86.6% expressed a desire to leave the profession. Additionally, the study found that 48.5% of the participants had had at least one abortion, nearly 30% had contracted sexually transmitted diseases, and more than 50% had a steady partner. A positive finding was that 93% of the prostitutes used condoms in their sexual relations. Condom use was associated with a lower prevalence of sexually transmitted diseases, which stood at 28.9%. The research also highlighted that 70% of women with depressive symptoms consumed alcohol and that 32.2% practiced a religion, which acted as a protective factor against depression.

The study titled "Transtorno Mental Comum em Acompanhantes de Pacientes em Internação Hospitalar de Curto e Médio Período: Um Estudo Transversal," published in the Revista Multidebates in June 2020, aimed to evaluate the prevalence of common mental disorder (CMD) in companions of patients hospitalized for short or medium periods. This cross-sectional study was conducted in a general hospital in Greater São Paulo in 2019, with a sample of 272 individuals, using the Self-Reporting Questionnaire (SRQ-20), globally validated. The results showed that 41.2% of the companions had CMD. The highest prevalence was observed in those who were the patient's children (49.1%), women (44.8%), aged 40 to 59 years (45.1%), who had another professional occupation (42%), suffered from a chronic disease (51.1%), and did not engage in physical activity (46.6%). The three sectors evaluated showed that the green sector, the first admission area, had the highest prevalence of CMD (49.5%).

In a cross-sectional study conducted in Shenyang and Guangzhou, China, in 2017, it was found that 25.25% of transgender sex workers exhibited high levels of depression. The study, which included 198 participants, used a structured questionnaire to assess background characteristics, self-esteem, feelings of defeat and entrapment, and depression. The results showed a negative correlation between self-esteem and depression, as well as between self-esteem and feelings of defeat and entrapment. Additionally, it was found that feelings of entrapment and defeat fully mediated the relationship between self-esteem and depression.

Anxiety

Anxiety is one of the most common mental disorders among sex workers due to constant exposure to high-risk situations such as violence, sexual coercion, and stigmatization. Studies have shown that sex workers exhibit significantly higher rates of anxiety symptoms compared to the general population. The prevalence of anxiety in this group can be related to multiple factors, including childhood abuse, workplace violence, and lack of social support. Additionally, sex workers often face health issues such as sexually transmitted infections and HIV, which can exacerbate their anxiety. Treating anxiety in sex workers requires a comprehensive approach that addresses both their physical and mental health through cognitive-behavioral therapy, psychological support, and, in some cases, medication.

The environment in which these women work, often characterized by a lack of security and instability, contributes to a constant sense of danger and alertness. Anxiety can manifest in a variety of symptoms, including panic attacks, irrational fear, excessive worry, hypervigilance, and difficulty sleeping. Repeated exposure to traumatic events, such as physical and sexual assaults, can also lead to the development of post-traumatic stress disorder (PTSD), which often coexists with anxiety.

Specific research, such as the study conducted in KwaZulu-Natal, South Africa, found that 78.4% of sex workers exhibited anxiety symptoms according to the Self Reporting Questionnaire (SRQ 20). This study also revealed that 72% of sex workers had experienced violence and 69% had suffered childhood abuse. These traumatic factors significantly contribute to the development of anxiety disorders and other mental health problems.

Difficulty in forming emotional bonds

“There are clients who fall in love with us, and we fall in love with the client. I have cried for love and argued with the client, and then I was left crying. So I had to charge and didn’t want to charge. I would go to the hotel and had to earn the money, and I cried... But then he changed me for a younger one, what can you do... I keep thinking, will there ever be a man who says, Bianca, let's get married?... You can’t fall in love. If you see yourself getting attached, you have to get out, you can't stay.”

Bianca, a prostitute from Curitiba

Women involved in prostitution tend to be characterized by insecure attachment and cognitions marked by emotional deprivation, distrust, fear of abandonment, feelings of unworthiness of love, and submission to others' control. These factors can result in social isolation and difficulties in relational commitment, particularly in the context of romantic relationships. However, interviews with these women revealed that almost three-quarters of them reported maintaining a relationship with a person who represented a significant source of support, well-being, and could act as a catalyst for change. Nonetheless, their support network seems to depend on a specific person or, at least, a very limited number of people. Another significant finding of the study is that when women reveal their involvement in prostitution to their loved ones, the latter tend to position themselves as positive actors in the change process rather than being a source of rejection and stigmatization. Direct interventions with loved ones should inform them that the support they can provide to these women is necessary.

Most women (78%) reported that sex work negatively affected their personal romantic relationships, mainly due to issues of lying, trust, guilt, and jealousy. A small number of women reported positive impacts of sex work, such as better sexual self-esteem and confidence. About half of the women were in a relationship at the time of the study, and of these, 51% reported that their partner knew the nature of their work. 77% of single women chose to remain single due to the nature of their work. Many women used mental separation as a coping mechanism to manage the tensions between sex work and their personal relationships.

The main ways in which sex work negatively affected women in relationships included dishonesty, distrust, jealousy, stigma, and pragmatic issues. Women in relationships often lied to their partners about the nature of their work, causing guilt and trust issues. Partners who knew about the women's work often experienced jealousy and misunderstandings due to the stigma associated with the sex industry.

More than half of the women in the study were single, primarily by choice, due to the nature of their work. Some women chose to remain single because they were not comfortable with the idea of having a relationship while working in the sex industry, or because they felt their partners would not be comfortable with their work.

About half of the women mentioned the need to maintain a distinction between their work and personal lives, using separation as a coping mechanism. More than half of the women found it difficult to mentally separate their work lives from their personal lives. Some strategies included not socializing with other sex workers outside of work and using condoms with clients but not with romantic partners. The findings of this study coincide with and expand on previous studies that also found that women working in the sex industry commonly report negative impacts on their relationships due to issues of dishonesty, trust, and guilt. The stigma associated with the sex industry was a significant barrier in the personal relationships of sex workers, leading to issues of support and understanding from their partners.

Social isolation

The mental health of sex workers is affected by a variety of factors, including social isolation, loneliness, and the social stigma associated with their occupation. These factors not only influence their emotional well-being but also interact with structural aspects such as criminalization and violence. The mode of work, whether solitary or with colleagues, also plays an important role in their daily experience and mental health. The lack of information and the infantilizing treatment they often receive contribute to a negative self-image and the perception of being unable to make decisions about their own lives, further exacerbating mental health issues in this group.

Social isolation and loneliness have a strong impact on the mental health of sex workers. A study conducted by the "European Sex Workers' Rights Alliance" showed that more than 70% of respondents considered that isolation greatly affects mental health. The mode of sex work can also influence their ability to work with colleagues or individually. Focus group participants indicated that the inherent loneliness of escorting was difficult to manage, while a participant who worked on the streets with colleagues mentioned enjoying having people around. A sex worker in Finland expressed that upon entering this industry, the lack of information is so great and the loneliness is so intense that it deeply affects them. Another impact of social stigma on mental health is the underlying assumption that sex workers are victims. A sex worker in Finland commented that they are not asked for their opinion or listened to, and that others make decisions for them, assuming they are incapable of choosing for themselves, which contributes to infantilization that can generate negative self-images and negatively affect mental health. Stigma acts as an umbrella factor that intertwines with many other structural factors influencing the mental health of sex workers, such as criminalization or violence.

Low self-esteem

Low self-esteem is a significant factor in the mental health of many people, and among sex workers, this issue can be especially pronounced. Self-esteem, defined as the value a person places on themselves, influences how they perceive and relate to the world. In the context of sex workers, low self-esteem is often related to experiences of rejection, social stigmatization, and traumatic situations. These women may face a cycle of self-criticism and personal worthlessness, exacerbated by discrimination and marginalization in their daily lives.

People with low self-esteem are more susceptible to manipulation and exploitation by pimps and other exploiters. There is a connection between low self-esteem and prostitution. In some cases, pimps use underage sex workers to recruit other residents of group homes. Sexual abuse can have a significant impact on self-esteem. Adopted individuals and those who have suffered sexual abuse tend to experience low self-esteem and difficulties in relationships.

Numerous studies have shown that low self-esteem is closely linked to a range of mental health problems, such as depression and anxiety. Sex workers with low self-esteem may feel trapped in their circumstances, unable to see a viable way out, reinforcing feelings of defeat and hopelessness. This cycle of negativity can be difficult to break without adequate support and intervention strategies that address both emotional aspects and social contexts that perpetuate low self-esteem.

The study "Sex work and three dimensions of self-esteem: self-worth, authenticity and self-efficacy" analyzes the relationship between sex work and self-esteem. The study uses a heterogeneous sample of 218 Canadian sex workers providing services in various locations, utilizing a three-dimensional framework of self-esteem: self-worth, authenticity (being oneself), and self-efficacy (competence).

Sex work is assumed to have a negative effect on self-esteem, expressed almost exclusively as low self-esteem due to its social unacceptability, despite the diversity of people, positions, and roles within the sex industry. In this study, a heterogeneous sample of 218 Canadian sex workers delivering services in various locations was asked how their work affected their sense of self. Using a thematic analysis based on a three-dimensional conception of self-esteem, we shed light on the relationship between engagement in sex work and self-esteem. The findings demonstrate that the relationship between sex work and self-esteem is complex: most participants discussed multiple dimensions of self-esteem and often spoke about how sex work had both positive and negative effects on their sense of self. Social background factors, the location of work, and life events and experiences also had an effect on self-esteem. Future research should adopt a more complex approach to understanding these issues by considering elements beyond self-esteem, such as authenticity and self-efficacy, and examining how the backgrounds and individual motivations of sex workers intersect with these three dimensions.

In a study titled "Evaluation of Self-Esteem of Female Sex Workers," focusing on analyzing the self-esteem of sex workers in Campina Grande-PB, the results showed that these women's self-esteem is low, influenced by the social stigma associated with prostitution and personal factors such as motherhood, family context, and age. Additionally, the study noted that younger workers charged more for their services than older ones, showing an economic impact of age on their profession.

Cultural differences

In the article "Self-esteem and cognitive distortion among women involved in prostitution in Malaysia," published in Procedia Social and Behavioral Sciences (2010), authors Rohany Nasir et al. examine how self-esteem and cognitive distortions vary among Muslim and non-Muslim women in Malaysia. Using the Rosenberg Self-Esteem Scale and Briere's Cognitive distortion Scale, the study reveals that Muslim prostitutes have significantly lower self-esteem and higher cognitive distortions compared to their non-Muslim counterparts. Additionally, a negative correlation was found between self-esteem and cognitive distortion, suggesting that higher self-esteem is associated with lower cognitive distortions.

Cognitive impairment

Research titled "Screening for Traumatic Brain Injury in Prostituted Women" highlights that violence is a predominant aspect of prostitution and a significant cause of TBI. 95% of participants had suffered head injuries, frequently as a result of being hit with objects or having their heads slammed against surfaces. Notably, 61% of the head injuries occurred while engaged in prostitution. The study documents both acute and chronic symptoms associated with these injuries, including dizziness, depression, headaches, sleep problems, concentration and memory difficulties, trouble following instructions, low frustration tolerance, fatigue, and changes in appetite and weight.

The study highlights the importance of screening for Traumatic brain injury (TBI) to ensure effective care for prostituted women. The authors note that TBIs, often caused by blows to the head or violent shaking, are common in interpersonal assaults, more than in accidents or falls. Additionally, head injuries are frequent in intimate partner violence (IPV), and women in prostitution often experience high rates of this type of violence.

Treatment

Psychotherapy for these women must be tailored to their specific needs, considering the use of crisis interventions and the building of coping skills during severe stress episodes. During periods of milder symptoms, a psychodynamic approach focused on self-reflection and deep exploration can be employed. The therapeutic relationship is necessary to establish trust and safety, allowing patients to explore their experiences and develop healthier coping mechanisms. Understanding transference and countertransference is essential for effective treatment, and clear professional boundaries must be maintained to avoid breaches that could harm the therapeutic relationship.

Long-term psychological effects

Transitioning from life in prostitution to life outside this activity involves profound psychological issues. The experience of having worked in the sex industry carries a series of long-term repercussions that affect mental and emotional health. In the text "Life After Prostitution" by Bethany St. James, the psychological impact of her experience in the adult entertainment industry is described. Although superficially the industry seemed benevolent, it was actually extremely damaging and unhealthy.

Upon leaving the industry, St. James faced an identity crisis, having spent 20 years in an environment that, though incomprehensible to outsiders, made sense to her. Leaving this life meant losing her identity and feeling disoriented in the real world. This lack of identity outside of work left her emotionally unstable, unable to relate to people outside the business. Removing the facade she had built as Bethany St. James left her feeling vulnerable and exposed. Everyday tasks began to trigger panic attacks, leading her to believe she was experiencing a mental breakdown. Seeking a new identity through her Christian faith and church participation did not provide the expected comfort, as her past experiences significantly differentiated her from her new peers, causing isolation and judgment from the religious community.

These emotional and social problems culminated in the appearance of severe PTSD symptoms. Comparing herself to her husband, a veteran with war-related PTSD, revealed that her form of PTSD was opposite to his: while he couldn't turn off his emergency response system, she didn't know how to react to normal situations after living in a constant state of alert. Cognitive therapy revealed that St. James had developed coping mechanisms that allowed her to neutralize normal emotional responses, making stressful situations seem routine. This emotional imbalance prevented her from recognizing the damage she had inflicted on herself over the years. The diagnosis of severe PTSD made her understand that her inability to perceive her experiences as traumatic was part of the problem. Not feeling that she had lived through traumatic events contrasted with others' perceptions, who saw her experiences as clearly traumatic. Therapy helped her process and heal, allowing her to understand and accept the complexity of her past and present life.

The study "Symptoms of Posttraumatic Stress Disorder and Mental Health in Women Who Escaped Prostitution and Helping Activists in Shelters," published in 2008, analyzes women who escaped prostitution, activists helping them in shelters, and a control group. The researchers found that former prostitutes exhibited significantly higher levels of PTSD symptoms, stress, somatization, depression, fatigue, sleep problems, smoking, and alcoholism compared to the other two groups. Activists also showed higher levels of tension, sleep problems, and smoking, and more frequent and severe PTSD symptoms than the control group.

The research concludes that participation in prostitution increases the risk of exposure to violence, which can cause psychological trauma in both the women involved and those who help them. These effects can be long-lasting, and the need to develop methods to assess and mitigate vicarious trauma in workers assisting prostitution victims is suggested. Additionally, the importance of early diagnosis and treatment is highlighted to reduce the social and economic burden of PTSD.

Case studies

Prostitutes of Minas Gerais

A cross-sectional study conducted in Minas Gerais evaluated the prevalence of common mental disorders (CMD) and associated factors in a group of prostitutes. The Self-Reporting Questionnaire (SRQ-20) was used to interview 216 women registered with the Prostitutes' Association of Minas Gerais (Aprosmig) between November 2012 and May 2013. The study analyzed sociodemographic characteristics and aspects of sex work, using the chi-squared test to examine the association between categorical variables and the presence of CMD, and employing a logistic regression model to identify factors associated with CMD. The overall prevalence of CMD was 57.9%, being more frequent in women with low education, history of physical violence, and early entry into prostitution. Women with less than eight years of schooling had twice the likelihood of developing CMD (OR = 2.05), and those with a history of physical violence also showed a significantly higher likelihood (OR = 2.18). The study concludes the need to improve healthcare for this group, given the high rates of CMD compared to the general population.

Women trafficked for sexual exploitation

The study titled "A Study on the Psychological Effects on Women Who Were Trafficked for Sexual Exploitation" addresses the psychological consequences experienced by women victims of trafficking for sexual exploitation. The research is based on various documentaries available on YouTube, including "Trafficking of Women for Sexual Exploitation" and "Amazonas Has a Human Trafficking Route Without Oversight." Human trafficking is a serious crime that infringes on women's rights, making them vulnerable in various psychological aspects. According to the UN, human trafficking generates $32 billion annually, with 85% coming from sexual exploitation and 98% of victims being women. The Palermo Protocol defines human trafficking as the recruitment, transportation, and exploitation of people through coercion, fraud, or abuse of vulnerability. This crime can involve luring and prolonged exploitation, causing severe psychological harm to the victims. Trafficked women generally come from regions with high poverty rates and low education, making them easy targets for traffickers who promise better living conditions abroad.

The study's methodology is exploratory and qualitative, using documentary data and victim testimonies. The analyzed documentaries recount real stories of suffering and exploitation, highlighting psychological effects categories such as objectification, desire for death, fear, fear of death, pain/suffering, and sadness. The results show that victims suffer deep psychological traumas, including depression, anxiety, suicide attempts, and post-traumatic stress disorder. Psychology plays a crucial role in the recovery of these women, helping them overcome traumas and rebuild their lives. The study concludes that trafficking of women for sexual exploitation is a continuous violence crime causing long-lasting psychological harm.

Risk factors study

The systematic review "Invisible and Stigmatized: A Systematic Review of Mental Health and Risk Factors Among Sex Workers," published in Acta Psychiatrica Scandinavica, examines the mental health and associated risk factors in sex workers (SW). The research, conducted by Laura Martín-Romo, Francisco J. Sanmartín, and Judith Velasco, analyzes studies published between 2010 and 2022 in various databases. Of 527 studies identified, 30 met the inclusion criteria.

The review highlights the prevalence of mental health issues among SWs, with depression being the most common problem, followed by anxiety, substance abuse, and suicidal ideation. SWs are exposed to multiple occupational risks, including violence and high-risk sexual behaviors, and face significant barriers to accessing health services due to stigma. SWs have higher probabilities of being diagnosed with mood disorders, with depression rates ranging between 50% and 88%. Anxiety affects between 13.6% and 51% of SWs, while post-traumatic stress disorder (PTSD) has a prevalence between 10% and 39.6%.

Substance abuse is common, with problematic alcohol use reported between 36.7% and 45.4% of SWs. Women are the majority in sex work, and lack of social support is associated with poorer psychological adaptation. Violence is a significant risk factor, with studies indicating that SWs experience high levels of violence, contributing to mental health problems. The review suggests that unfavorable working conditions, lack of access to health services, and stigma play a crucial role in the poor mental health of SWs. The review notes the need for longitudinal studies and a better understanding of the clinical backgrounds of SWs to determine the impact of sex work on mental health.

AESHA study in Vancouver

In a study conducted in Vancouver, Canada, titled An Evaluation of Sex Workers Health Access (AESHA), it was found that 48.8% of the sex workers surveyed reported having ever been diagnosed with a mental health issue, with the most common diagnoses being depression (35.1%) and anxiety (19.9%). This study used interviewer-administered questionnaires and bivariate and multivariable logistic regression analyses to evaluate the burden of mental health diagnoses and their correlations. The study's findings highlighted that sex workers with mental health diagnoses were more likely to identify as sexual/gender minorities (LGBTQ), use non-injection drugs, have experienced physical/sexual trauma in childhood, and work in informal or public spaces. These findings show the need for evidence-based interventions addressing the intersections between trauma and mental health, along with policies promoting access to safer workspaces and adequate health services. Sex workers often operate in environments characterized by insecurity and instability, contributing to a constant sense of danger and alertness. Anxiety can manifest in various symptoms, including panic attacks, irrational fears, excessive worry, hypervigilance, and sleep difficulties. Repeated exposure to traumatic events can lead to the development of post-traumatic stress disorder (PTSD), which often coexists with anxiety. The Vancouver study also revealed that sex workers with mental health diagnoses were more likely to have used non-injection drugs and experienced physical or sexual violence, both in childhood and adulthood. These traumatic factors significantly contribute to the development of anxiety disorders and other mental health issues. Additionally, identifying as a sexual/gender minority was strongly associated with mental health diagnoses, due to the structural discrimination and stigma faced by these individuals.

Non-reproductive sexual behavior in animals

Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non-copulatory mounting (without insertion, or by a female, or by a younger male who does not yet produce semen), oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub participants, as well as sex with dead animals.

Social interaction and bonding

Lions are known to engage in sex to create bonds and interact with each other. Lions live in a social group known as a pride that consists of 2–18 females and 1–7 males. The females found in these prides were born into the pride. The males enter the pride from other prides. The success of reproduction for each individual lion is dependent on the number of male lions found in their social group. Male lions create coalitions and search for prides to take over. Successful coalitions have usually created a strong bond with each other and will take over prides. Once winning in a competition, all current males in the pride will be kicked out and left to find another pride. While in search of another pride these males will often engage in sexual behavior with each other; creating a strong bond in this new coalition created.

Sex plays a fundamental role in the social lives of bonobos. Female bonobos have been observed to engage in sexual activities to create bonds with dominant bonobos. Having created this bond with the male, they will share food with each other and not compete with each other. All members of a bonobo group are potential sex partners, regardless of age combination or gender combination. In "Biological Exuberance," Bagemihl writes: "when new females (usually adolescents) join a troop, they often pair up with an older female with whom they have most of their sexual and affectionate interactions." In addition, bonobos need not limit themselves to a single partner: "These bonds need not be exclusive – either party may have sex with other females or males – but such mentorlike pairings can last for a year or more until the newcomer is fully integrated into the troop." Pairings between younger and older male bonobos are also common: "typically an adolescent male spreads his legs and presents his erect penis to an adult male, who takes the shaft in his hand and caresses it with up-and-down movements."

Social pairings between youth and adult bonobos happen across gender combinations: "Both adult males and females interact sexually with adolescents and juveniles (three-to-nine-year-olds). In fact, young females go through a five-to-six-year period sometimes referred to as adolescent sterility (although no pathology is involved) during which they actively participate in heterosexual mating (often with adults) but never get pregnant. Sexual behavior between adults and infants of both sexes is common - about a third of the time it is initiated by the infant and may involve genital rubbing and full copulatory postures (including penetration of an adult female by a male infant)."

Several species utilize sexual activity as a way to resolve disagreement. Bonobos are one species famously known for using sexual behavior as a means of resolution of social conflict.

In a study concentrated on primate conflict resolution, researchers wanted to observe primates in conflict. How primates coped and resolved conflicts was a main concern in this study. Researchers stated that after primates participated in a heated, physical fight; both primates involved in the fight would hug and have a mouth-to-mouth kiss. This action was considered as a demonstration of affection and reconciliation.

Reward system

Studies of the brain have proven that pleasure and displeasure are an important component in the lives of animals. It has been established that the limbic neural mechanism that generates reactions are very similar across all mammals. Many studies have concentrated on the brain reward system and how similar it is across mammals. Through extensive research, scientists have been able to conclude that the brain reward system in animals is extremely similar to that of humans. The mechanism of core pleasure reaction is significantly important for animals including humans.

Evolutionary principles have predicted that the reward system is part of the proximate mechanism underlying the behavior. Because animals possess a brain reward system they are motivated to perform in different ways by desire and reinforced by pleasure. Animals establish security of food, shelter, social contact, and mating because proximate mechanism, if they do not seek these necessities they will not survive.

All vertebrates share similarities in body structure; they all have a skeleton, a nervous system, a circulatory system, a digestive system and excretory system. Similar to humans, non-human animals also have a sensory system. The sensory system is responsible for the basic five senses from touch to tasting. Most of the physiological and biochemical responses found in animals are found in humans. Neurophysiologists have not found any fundamental difference between the structure and function of neurons and synapse between humans and other animals.

Case study

In a case study, female Japanese macaques were studied to find evidence of possible female copulatory orgasms. The frequency of orgasms did not correlate with the age or rank of the Japanese macaques. Researchers observed that the longer and higher number of pelvic thrusts, the longer copulation lasted. There was an orgasmic response in 80 of the 240 Japanese macaques studied.

Recent studies using positron emission tomography (PET) and magnetic resonance imaging (MRI) has provided evidence proving that chemical changes that occur with emotions are similar between humans and non-human animals. In a study comparing guinea pigs and humans, it was determined that the distress experienced by offspring separation in a guinea pig and a human going through depression activates the same region of the brain. The opiate receptor was also examined, allowing observation of the pleasure stimuli. In the procedure both a human and a rat had their receptors blocked with a certain drug. Once receptors were blocked, both the rat and the human were exposed to pleasurable food, but both were disinclined to eat the food.

Types of behavior

Engagements of sexual activities during non-breeding seasons have been observed in the animal kingdom. Dolphins and Japanese macaques are two of the many species that engage in sexual activities that do not lead to fertilization. Great varieties of non-copulatory mounting are expressed in several species. Male lions engage in mounting with other male lions, especially when in search of another pride. The varieties of mounting include mounting without erections, mounting with erection but no insertion, and mounting from the side.

Expressions of affection are displayed in the animal kingdom as well. Affectionate behaviors do not include insertion or genital rubbing, but are still seen as a manner of sexual behavior. An affectionate activity can be as simple as licking. Male lions are known for head rubbing, bats engage in licking, and mountain sheep rub horns and faces with each other. Kissing, touching of noses, mouths and muzzles have been witnessed in African elephants, walruses, and mountain zebras. Primates also engage in kissing that is incredibly similar to human display of kissing. Chimpanzees have full mouth-to-mouth contact, and bonobos kiss with their mouth open and mutual tongue stimulation. There are a variety of acts to show affection such as African elephants intertwining their trunks, giraffes engaging in "necking", and Hanuman langurs cuddling with each other in a front to back sitting position.

Non-penetrative genital stimulation is very common throughout the animal kingdom. Different forms of self and partner genital stimulation have been observed in the animal kingdom. Oral sex has been observed throughout the animal kingdom, from dolphins to primates. Bonobos have been observed to transition from a simple demonstration of affection to non-penetrative genital stimulation. Animals perform oral sex by licking, sucking or nuzzling the genitals of their partner. Another form of genital stimulation is masturbation. Masturbation is widespread throughout mammals for both males and females. It is less common in birds. There are several techniques, in which animals engage in masturbation from using paws, feet, flippers, tails, and sometimes using objects like sticks, pebbles, and leaves. Masturbation occurs more often in primate species with large testes relative to their body size.

Anal insertion

Anal insertion with the penis (both in heterosexual and male homosexual dyads, i.e. pairs of animals) has been observed among some primate species. Male homosexual anal insertion has been recorded in Old World primate species, including gorillas, orangutans, and some members of the Macaca genus (namely, stumptail, rhesus, and Japanese macaques). It has also been recorded in at least two New World primate species, the squirrel monkey and the spider monkey. Morris (1970) also described one heterosexual orangutan dyad for whom all penetration was performed anally. However, the practice might have been a consequence of homosexual rearing, as the male orangutan in this dyad had had extensive same–sex experience. Anal insertion has also been observed among bonobo, with the observation described as 'anal intromission'. 

A case of male homosexual anal insertion with the finger has also been reported among orangutans, and Bruce Bagemihl mentions it as one of the homosexual practices recorded at least once among male chimpanzees.

Autoeroticism or masturbation

Many animals, both male and female, masturbate, both when partners are available and otherwise. For example, it has been observed in cats, dogs, male Cape ground squirrels, male deer, rhinoceroses, boars, male monkeys and otters.

A review from the University of Pennsylvania School of Veterinary Medicine says:

[The] behavior known within the horse breeding industry as masturbation ... involves normal periodic erections and penile movements. This behavior, both from the descriptive field studies cited above and in extensive study of domestic horses, is now understood as normal, frequent behavior of male equids.[39] Attempting to inhibit or punish masturbation, for example by tying a brush to the area of the flank underside where the penis rubs into contact with the underside, which is still a common practice of horse managers regionally around the world, often leads to increased masturbation and disturbances of normal breeding behaviour.

Castration does not prevent masturbation, as it is observed in geldings. Masturbation is common in both mares and stallions, before and after puberty.

Sexologist Havelock Ellis in his 1927 Studies in the Psychology of Sex identified bulls, goats, sheep, camels and elephants as species known to practice autoeroticism, adding of some other species:

I am informed by a gentleman who is a recognized authority on goats, that they sometimes take the penis into the mouth and produce actual orgasm, thus practicing autofellatio. As regards ferrets ... "if the bitch, when in heat, cannot obtain a dog [ie, male ferret] she pines and becomes ill. If a smooth pebble is introduced into the hutch, she will masturbate upon it, thus preserving her normal health for one season. But if this artificial substitute is given to her a second season, she will not, as formerly, be content with it." ... Blumenbach observed a bear act somewhat similarly on seeing other bears coupling, and hyenas, according to Ploss and Bartels, have been seen practicing mutual masturbation by licking each other's genitals.

In his 1999 book, Biological Exuberance, Bruce Bagemihl documents that:

Autoeroticism also occurs widely among animals, both male and female. A variety of creative techniques are used, including genital stimulation using the hand or front paw (primates, Lions), foot (Vampire Bats, primates), flipper (Walruses), or tail (Savanna Baboons), sometimes accompanied by stimulation of the nipples (Rhesus Macaques, Bonobos); auto-fellating or licking, sucking and/or nuzzling by a male of his own penis (Chimpanzees, Savanna Bonobos, Vervet Monkeys, Squirrel Monkeys, Thinhorn Sheep, Bharal, Aovdad, Dwarf Cavies); stimulation of the penis by flipping or rubbing it against the belly or in its own sheath (White-tailed and Mule Deer, Zebras and Takhi); spontaneous ejaculations (Mountain Sheep, Warthogs, Spotted Hyenas); and stimulation of the genitals using inanimate objects (found in several primates and cetaceans).

Many birds masturbate by mounting and copulating with tufts of grass, leaves or mounds of earth, and some mammals such as primates and dolphins also rub their genitals against the ground or other surfaces to stimulate themselves.

Autoeroticism in female mammals, as well as heterosexual and homosexual intercourse (especially in primates), often involves direct or indirect stimulation of the clitoris ... This organ is present in the females of all mammalian species and several other animal groups.

and that:

Apes and Monkeys use a variety of objects to masturbate with and even deliberately create implements for sexual stimulation ... often in highly creative ways.

David Linden, professor of neuroscience at Johns Hopkins University, remarks that:

... perhaps the most creative form of animal masturbation is that of the male bottlenose dolphin, which has been observed to wrap a live, wriggling eel around its penis.

Among elephants, female same-sex behaviours have been documented only in captivity where they are known to masturbate one another with their trunks.

Oral sex

Animals of several species are documented as engaging in both autofellatio and oral sex. Although easily confused by laypeople, autofellatio and oral sex are separate, sexually oriented behaviors, distinct from non-sexual grooming or the investigation of scents.

Autofellatio and oral sex in animals is documented in spiders (Darwin's bark and widow), brown bears, stump-tailed macaques, Tibetan macaques, wolves, goats, primates, bats, cape ground squirrels and sheep (see section Masturbation for details).

In the greater short-nosed fruit bat, copulation by males is dorsoventral and the females lick the shaft or the base of the male's penis, but not the glans, which has already penetrated the vagina. While the females do this, the penis is not withdrawn and research has shown a positive relationship between length of the time that the penis is licked and the duration of copulation. Post copulation genital grooming has also been observed.

Homosexual behavior

Two male mallards, Anas platyrhynchos. Mallards have rates of male-male sexual activity that are unusually high for birds, in some cases, as high as 19% of all pairs in a population.

The presence of same-sex sexual behaviour was not scientifically reported on a large scale until recent times. Homosexual behaviour does occur in the animal kingdom outside humans, especially in social species, particularly in marine birds and mammals, monkeys, and the great apes. As of 1999, the scientific literature contained reports of homosexual behavior in at least 471 wild species.

Homosexual behavior exists on a spectrum, and may or may not involve insertion. Apart from sexual activity, it can refer to homosexual pair-bonding, homosexual parenting and homosexual acts of affection. Engaging in homosexual behavior may allow species to obtain benefits such as gaining practice, relieving tension, and experiencing pleasure. Georgetown University professor Janet Mann has specifically theorised that homosexual behaviour, at least in dolphins, is an evolutionary advantage that minimizes intraspecies aggression, especially among males.

After studying bonobos for his book Bonobo: The Forgotten Ape, primatologist Frans de Waal, a professor of psychology at Emory University in Atlanta, says that such expressions of intimacy are consistent with the homosexual behaviour of what he terms "the erotic champions of the world". "Same-sex, opposite-sex — bonobos just love sex play," de Waal said in an interview. "They have so much sex, it gets boring."

Homosexual behaviour is found in 6–10% of rams (sheep) and associated with variations in cerebral mass distribution and chemical activity.

Approximately eight percent of [male] rams exhibit sexual preferences [that is, even when given a choice] for male partners (male-oriented rams) in contrast to most rams, which prefer female partners (female-oriented rams). We identified a cell group within the medial preoptic area/anterior hypothalamus of age-matched adult sheep that was significantly larger in adult rams than in ewes ...

Male bighorn sheep are divisible into two kinds: the typical males among whom homosexual behaviour, including intercourse, is common and "effeminate sheep", or "behavioural transvestites", which are not known to engage in homosexual behaviour.

Male-male copulation has been observed in captive penguins and homosexual behaviour has been observed among bats, in particular, the fruit bat.

Genital-genital rubbing

Genital-genital rubbing, or GG rubbing, among non-human animals is sexual activity in which one animal rubs his or her genitals against the genitals of another animal. The term GG rubbing is frequently used by primatologists to describe this type of sexual intimacy among female bonobos, and is stated to be the "bonobo's most typical sexual pattern, undocumented in any other primate". The term is sometimes used in reference to GG rubbing among male bonobos, under the term "penis fencing", which is the non-human form of frot that human males engage in. Such rubbing between males is thought, according to varying evolutionary theorists, to have existed before the development of hominids into humans and bonobos, and may or may not have occurred in the homosexual activity of both of these genetically related species.

Genital rubbing has been observed once among male orangutans and several times in a small group of lar gibbons, where two males thrust their genitals together, sometimes resulting in ejaculation in one of the partners. It has been observed among bull manatees, in conjunction with "kissing", and is also common among homosexually active mammals.

Inter-species sex

Some animals opportunistically mate with individuals of another species. This is more commonly observed in domesticated species and animals in captivity, possibly because captivity is associated with a decrease in aggression and an increase in sexual receptivity. Nevertheless, animals in the wild have been observed to attempt sexual activity with other species. It is mostly documented among species that belong to the same genus, but sometimes occurs between species of distant taxa. Alfred Kinsey cites reports of sexual activity involving a female eland with an ostrich, a male dog with a chicken, a male monkey with a snake, and a female chimpanzee with a cat.

A 2008 review of the literature found 44 species pairs that had been observed attempting interspecies mating, and 46 species pairs that had completed interspecies matings, not counting cases that had resulted in hybridization. Most were known from laboratory experiments, but field observations had also been made. It may result in fitness loss because of the waste of time, energy, and nutrients.

Male sea otters have been observed forcibly copulating with seals, and male seals have been observed forcibly copulating with penguins. Inter-species sexual behavior has also been observed in sea lions. Male grasshoppers of the species Tetrix ceperoi often mount other species of either sex and even flies, but are normally repelled by the larger females. Males of the spider mite species Panonychus citri copulate with female Panonychus mori mites almost as often as with their own species, even though it does not result in reproduction.

The Japanese macaque has been observed attempting to mate with the sika deer.

Sex involving juveniles

"Mock mating" of desert fox pups

In one reported observation, a male spotted hyena attempted to mate with a female hyena, but she succeeded in driving him off. He eventually turned to her 10-month-old cub, repeatedly mounting and ejaculating on it. The cub sometimes ignored this and sometimes struggled "slightly as if in play". The mother did not intervene.

It appears to be common in the Adélie penguin.

Among insects, there have been reports of immature females being forcibly copulated with.

Juvenile male chimpanzees have been recorded mounting and copulating with immature chimps. Infants in bonobo societies are often involved in sexual behaviour. Immature male bonobos have been recorded initiating genital play with both adolescent and mature female bonobos. Copulation-like contact between immature bonobo males and mature female bonobos increases with age and continues until the male bonobo has reached juvenile age. In contrast, adult gorillas do not show any sexual interest in juvenile or infant members of their species. Primates regularly have sex in full view of infants, juveniles and younger members of their species.

Necrophilia

Necrophilia describes when an animal engages in a sexual act with a dead animal. It has been observed in mammals, birds, reptiles and frogs. It sometimes occurs in the Adélie penguin. Homosexual necrophilia has been reported between two male mallard ducks. One duck was believed to be pursuing another duck with the goal of rape (a common aspect of duck sexual behaviour) when the second duck collided with a window and died immediately. The observer, Kees Moeliker, suggested that "when one died, the other one just went for it and didn't get any negative feedback—well, didn't get any feedback." The case study earned Moeliker an Ig Nobel Prize in biology.
