Sexual addiction, also known as sex addiction or sexual dependence, is compulsive participation or engagement in sexual activity, despite negative consequences.[3] In a clinical setting, sexual dependence may also refer to a conceptual model that is used to assess people who report being unable to control their sexual urges, behaviors, or thoughts. Related models of pathological sexual behavior include hypersexuality, erotomania, nymphomania, satyriasis, Don Juanism (or Don Juanitaism), and paraphilia-related disorders.[4][5][6]

Medical studies and related opinions vary among professional psychologists, sociologists, neurobiologists, sexologists, researchers, and other specialists on the classification and identification of sexual addictions. Diagnostic models, which use the pharmacological model of addiction (this model associates addiction with drug-related concepts, particularly physical dependence, drug withdrawal, and drug tolerance[7]), do not currently include diagnostic criteria to identify sexual addictions in a clinical setting. In the alternative reward-reinforcement model of addiction, which uses neuropsychological concepts to characterize addictions, sexual addictions are identifiable and well-characterized.[8][9] In this model, addictive drugs are characterized as those which are both reinforcing and rewarding (i.e., activates neural pathways associated with reward perception).[7] Addictive behaviors (those which can induce a compulsive state) are similarly identified and characterized by their rewarding and reinforcing properties.

In a clinical setting, proponents of the sexual addiction model draw analogies between hypersexuality and substance addiction or negative behavioral patterns similar to gambling addiction, recommending 12-step and other addiction-based methods of treatment. Other explanatory models of hypersexuality include sexual compulsivity and sexual impulsivity.

Models[edit]

Diagnostic models[edit]

DSM[edit]

The American Psychiatric Association publishes and periodically updates the Diagnostic and Statistical Manual of Mental Disorders (DSM), a widely recognized compendium of mental health diagnostics.[7]

The version published in 1987 (DSM-III-R), referred to "distress about a pattern of repeated sexual conquests or other forms of nonparaphilic sexual addiction, involving a succession of people who exist only as things to be used."[10] The reference to sexual addiction was subsequently removed.[11] The DSM-IV-TR, published in 2000 (DSM-IV-TR), did not include sexual addiction as a mental disorder.[12] The DSM-IV-TR included a miscellaneous diagnosis called Sexual Disorders Not Otherwise Specified, stating : "distress about a pattern of repeated sexual relationships involving a succession of lovers who are experienced by the individual only as things to be used." (Other examples include: compulsive fixation on an unattainable partner, compulsive masturbation, compulsive love relationships, and compulsive sexuality in a relationship.)[12]

Some authors suggested that sexual addiction should be re-introduced into the DSM system;[13] however, sexual addiction was rejected for inclusion in the DSM-5, which was published in 2013.[14] Darrel Regier, vice-chair of the DSM-5 task force, said that "[A]lthough 'hypersexuality' is a proposed new addition...[the phenomenon] was not at the point where we were ready to call it an addiction." The proposed diagnosis does not make the cut as an official diagnosis due to a lack of research into diagnostic criteria for compulsive sexual behavior, according to the American Psychiatric Association.[15][16]

Borderline personality disorder[edit]

The American Psychiatric Association uses the Diagnostic and Statistical Manual of Mental Disorders (DSM) to define and classify mental illnesses and in the DSM-IV version of the document, it lists borderline personality disorder (BPD) as an Axis II – Cluster B personality disorder with the code 301.83. The DSM-5 dropped the multiaxial system, but BPD still retains the same numerical code of 301.83.[15] The World Health Organization's produces the International Classification of Diseases (ICD) and lists BPD under the name "Emotionally unstable personality disorder". The latest version of the document (ICD-10) lists the disorder in Chapter X which is reserved for "Disorders of adult personality and behaviour" and has the code F60.3.[17] The Chinese Society of Psychiatry uses the Chinese Classification of Mental Disorders (CCMD), which is in its third edition (CCMD-3) and has a diagnosis of "Nonorganic sexual dysfunction" (numerical code 52.9), of which sexual promiscuity may be a symptom. Personality disorders, Habit and impulse disorders, Psychosexual disorders in the CCMD-3 fall in Chapter 6 and under code 6.60 are listed the personality disorders. The CCMD-3 lists "impulsive personality disorder" (numerical code 60.4),[18] which is equivalent to what the DSM refers to as "borderline personality disorder" and what the ICD-10 refers to as "emotionally unstable personality disorder". All three classification manuals and documents list sexual promiscuity as a prevalent and problematic symptom for patients with this particular pathology. Hypersexuality along with high-risk sexual behaviour, seductive behaviour, and promiscuity are an often due to the marked impulsivity common to this group of patients. Individuals with borderline personality disorder (emotionally unstable personality disorder or impulsive personality disorder) not only are prone to promiscuity, but in many cases, co-morbid paraphilias and fetishistic behaviour are commonly associated with their sexual behaviours. Common paraphilic compulsions among individuals with this diagnosis include urolagnia ("golden showers"), sadomasochism, voyeurism autassassinophilia, partialism, biastophilia, and in some cases paraphilic drives may be more extreme and dangerous – such as erotophonophilia, necrophilia, pedophilia, and even anthropophagy. Both males and females with this personality disorder often have a strong desire and compulsion to get involved in illicit sex, affairs, and relationships with married or otherwise pre-attached individuals. Consequently individuals with borderline personality disorder often experience love and sexuality in perverse and violent qualities which they cannot integrate with the tender, intimate side of relationships.[19][20]

ICD[edit]

The World Health Organization produces the International Classification of Diseases (ICD), which is not limited to mental disorders. The most recent version of that document, ICD-10, includes "Excessive sexual drive" as a diagnosis (code F52.7), subdividing it into satyriasis (for males) and nymphomania (for females).[21]

CCMD[edit]

The Chinese Society of Psychiatry produces the Chinese Classification of Mental Disorders (CCMD), which is currently in its third edition – the CCMD-3 and Chapter 5 of the document lists "Physiological disorders related to psychological factors" and under code 52 are disorders that are "Nonorganic sexual dysfuction," and within that category are listed a number of disorders, one of which is "Other or unspecified sexual dysfunction" (numerical code 52.9).[22] This is roughly equivalent to the ICD-10 diagnosis of "Excessive sexual drive" (F52.7), "Other sexual dysfunction, not caused by organic disorder or disease" (F52.8) and "Unspecified sexual dysfunction, not caused by organic disorder or disease" (F52.9).[23]

Symptoms and diagnostic criteria[edit]

Several mental health providers have proposed various, but similar, criteria for diagnosing sexual addiction, including Patrick Carnes,[24] and Aviel Goodman,[25] None of these proposals has been adopted into any official diagnostic manual, however.

During the update of the Diagnostic and Statistical Manual to version 5 (DSM-5), the American Psychiatric Association rejected two independent proposals for inclusion.[citation needed]

The International Classification of Diseases (ICD-10) of the World Health Organization, however, does include an entry for "Excessive Masturbation"[26] and another for "Excessive Sexual Drive."[17]

In 2011, the American Society of Addiction Medicine (ASAM), the largest medical consensus of physicians dedicated to treating and preventing addiction,[27] redefined addiction as a chronic brain disorder[28] which for the first time broadened the definition of addiction from substances to include addictive behaviors and reward-seeking, such as gambling and sex.[29]

Reward-reinforcement model[edit]

For context or background information on the psychology concepts described in these sections, see Operant conditioning.

Current research on sexual addiction within the context of the reward-reinforcement model indicates that it is well-characterized as an addiction (in this context, a compulsive behavior)[8][9] and that it develops through the same biomolecular mechanisms that induce drug addictions;[8][30] specifically, sexual activity has been shown to be highly rewarding[9][30] and naturally reinforcing.[9][30] Excessive activation of the associated reward-reinforcement mechanisms has been directly implicated in the development of compulsive (i.e., an addiction to) sexual behavior.[8][9]

In humans, a dopamine dysregulation syndrome, characterized by drug-induced compulsive engagement in sexual activity or gambling, has also been observed in some individuals taking dopaminergic medications.[8]

Biomolecular mechanisms[edit]

Part of this section is transcluded from FOSB. (edit | history)

Current experimental models of addiction to natural rewards and drug reward demonstrate common alterations in gene expression in the mesocorticolimbic projection.[8][31] ΔFosB is the most significant gene transcription factor involved in addiction, since its viral or genetic overexpression in the nucleus accumbens is necessary and sufficient for most of the neural adaptations and plasticity that occur;[31] it has been implicated in addictions to alcohol, cannabinoids, cocaine, nicotine, opioids, phenylcyclidine, and substituted amphetamines.[8][31][32] ΔJunD is the transcription factor which directly opposes ΔFosB.[31] Increases in nucleus accumbens ΔJunD expression can reduce or, with a large increase, even block most of the neural alterations seen in chronic drug abuse (i.e., the alterations mediated by ΔFosB).[31]

ΔFosB also plays an important role in regulating behavioral responses to natural rewards, such as palatable food, sex, and exercise.[9][31] Natural rewards, like drugs of abuse, induce ΔFosB in the nucleus accumbens, and chronic acquisition of these rewards can result in a similar pathological addictive state.[8][9] Thus, ΔFosB is also the key transcription factor involved in addictions to natural rewards as well,[8][30] and sex addictions in particular, since ΔFosB in the nucleus accumbens is critical for the reinforcing effects of sexual reward.[9] Research on the interaction between natural and drug rewards suggests that psychostimulants and sexual reward possess cross-sensitization effects and act on common biomolecular mechanisms of addiction-related neuroplasticity which are mediated through ΔFosB.[8][30]

ΔFosB inhibitors (drugs that oppose its action) may be an effective treatment for addiction and addictive disorders.[33]

Treatment[edit]

Behavioral therapy[edit]

Cognitive behavioral therapy is a common form of behavioral treatment for addictions and maladaptive behaviors in general.[medical citation needed] Certified Sex Addiction Therapists (CSAT) – a group of sexual addiction therapists licensed by the International Institute for Trauma and Addiction Professionals – offer specialized behavioral therapy designed specifically for sexual addiction.[34][35] Involvement in twelve-step programs, like Sex Addicts Anonymous or other groups, can also serve as an adjunct therapy to supplement clinical treatment.

Pharmacological treatments[edit]

SSRIs have been used in research studies and off-label to treat symptoms of overly frequent sexual urges, but their effects are not always robust.[medical citation needed] These drugs affect sexual behavior primarily by reducing libido (sexual desire).[medical citation needed]

History[edit]

Sex addiction as a term first emerged in the mid-1970s when various members of Alcoholics Anonymous sought to apply the principles of 12-Steps toward sexual recovery from serial infidelity and other unmanageable compulsive sex behaviors that were similar to the powerlessness and un-manageability they experienced with alcoholism.[36] Multiple 12-step style self-help groups now exist for people who identify as sex addicts, including Sex Addicts Anonymous, Sexaholics Anonymous, Sex and Love Addicts Anonymous, and Sexual Compulsives Anonymous.

The controversy surrounding sexual addiction is centered around its identification, through a diagnostic model, in a clinical setting. As noted in current medical literature reviews, compulsive sexual behavior has been observed in humans;[8][9] drug-induced compulsive sexual behavior has also been noted clinically in some individuals taking dopaminergic drugs.[8] Moreover, current medical research involving neuropsychological models has identified sexual addictions (i.e., the compulsive engagement in sexual behavior despite negative consequences) as a true form of addiction (i.e., it possesses all the necessary characteristics to classify it as one) in animal models.[8][9] Since current diagnostic models use drug-related concepts as diagnostic criteria for addictions,[7] these are ill-suited for modelling compulsive behaviors in a clinical setting.[8] Consequently, diagnostic classification systems, such the DSM, do not include sexual addiction as a diagnosis because there is currently "insufficient peer-reviewed evidence to establish the diagnostic criteria and course descriptions needed to identify these behaviors as mental disorders".[15]

There have been debates regarding the definition and existence of sexual addictions.[37][38] Some experts regard sexual addiction as a medical form of clinical addiction, directly analogous to alcohol and drug addictions. Other experts believe that sexual addiction is actually a form of obsessive compulsive disorder and refer to it as sexual compulsivity.[39] Still other experts believe that sex addiction is itself a myth, a by-product of cultural and other influences.[40][41] Some who express doubts about the existence of sex addiction argue that the condition is instead a way of projecting social stigma onto patients.[40] For example, one clinician, Marty Klein, states that "the concept of sex addiction provides an excellent example of a model that is both sex-negative and politically disastrous."[42]:8 Klein singled out a number of features that he considered crucial limitations of the sex addiction model[42]:8 and stated that the diagnostic criteria for sexual addiction are easy to find on the internet.[42]:9 Drawing on the Sexual Addiction Screening Test, he stated that "the sexual addiction diagnostic criteria make problems of nonproblematic experiences, and as a result pathologize a majority of people."[42]:10

In popular culture[edit]

Sexual addiction has been the main theme in films such as 2001 film Diary of a Sex Addict, 2005 film I Am a Sex Addict, 2006 film Black Snake Moan, 2008 film Confessions of a Porn Addict, 2011 film Shame and others.

The defining feature of addiction is compulsive, out-of-control drug use, despite negative consequences. ...Addictive drugs are both rewarding and reinforcing. A reward is a stimulus that the brain interprets as intrinsically positive or as something to be approached. A reinforcing stimulus is one that increases the probability that behaviors paired with it will be repeated. Not all reinforcers are rewarding; for example, a negative or punishing stimulus might reinforce avoidance behaviors. ... Familiar pharmacologic terms such as tolerance, dependence, and sensitization are useful in describing some of the time-dependent processes that underlie addiction. ...
    Dependence is defined as an adaptive state that develops in response to repeated drug administration, and is unmasked during withdrawal, which occurs when drug taking stops. Dependence from long-term drug use may have both a somatic component, manifested by physical symptoms, and an emotional–motivation component, manifested by dysphoria. While physical dependence and withdrawal occur with some drugs of abuse (opiates, ethanol), these phenomena are not useful in the diagnosis of addiction because they do not occur with other drugs of abuse (cocaine, amphetamine) and can occur with many drugs that are not abused (propranolol, clonidine). The official diagnosis of drug addiction by the Diagnostic and Statistic Manual of Mental Disorders (2000), which makes distinctions between drug use, abuse, and substance dependence, is flawed. First, diagnosis of drug use versus abuse can be arbitrary and reflect cultural norms, not medical phenomena. Second, the term substance dependence implies that dependence is the primary pharmacologic phenomenon underlying addiction, which is likely not true, as tolerance, sensitization, and learning and memory also play central roles. It is ironic and unfornate that the Manual avoids use of the term addiction, which provides the best description of the clinical syndrome.

Cross-sensitization is also bidirectional, as a history of amphetamine administration facilitates sexual behavior and enhances the associated increase in NAc DA ... As described for food reward, sexual experience can also lead to activation of plasticity-related signaling cascades. The transcription factor delta FosB is increased in the NAc, PFC, dorsal striatum, and VTA following repeated sexual behavior (Wallace et al., 2008; Pitchers et al., 2010b). This natural increase in delta FosB or viral overexpression of delta FosB within the NAc modulates sexual performance, and NAc blockade of delta FosB attenuates this behavior (Hedges et al, 2009; Pitchers et al., 2010b). Further, viral overexpression of delta FosB enhances the conditioned place preference for an environment paired with sexual experience (Hedges et al., 2009). ... In some people, there is a transition from “normal” to compulsive engagement in natural rewards (such as food or sex), a condition that some have termed behavioral or non-drug addictions (Holden, 2001; Grant et al., 2006a). ... In humans, the role of dopamine signaling in incentive-sensitization processes has recently been highlighted by the observation of a dopamine dysregulation syndrome in some patients taking dopaminergic drugs. This syndrome is characterized by a medication-induced increase in (or compulsive) engagement in non-drug rewards such as gambling, shopping, or sex (Evans et al, 2006; Aiken, 2007; Lader, 2008)."

PMC 4040958. PMID 22641964. It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward. Pitchers and colleagues (2010) reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus. Next, the induction of c-Fos, a downstream (repressed) target of DeltaFosB, was measured in sexually experienced and naive animals. The number of mating-induced c-Fos-IR cells was significantly decreased in sexually experienced animals compared to sexually naive controls. Finally, DeltaFosB levels and its activity in the NAc were manipulated using viral-mediated gene transfer to study its potential role in mediating sexual experience and experience-induced facilitation of sexual performance. Animals with DeltaFosB overexpression displayed enhanced facilitation of sexual performance with sexual experience relative to controls. In contrast, the expression of DeltaJunD, a dominant-negative binding partner of DeltaFosB, attenuated sexual experience-induced facilitation of sexual performance, and stunted long-term maintenance of facilitation compared to DeltaFosB overexpressing group. Together, these findings support a critical role for DeltaFosB expression in the NAc in the reinforcing effects of sexual behavior and sexual experience-induced facilitation of sexual performance. ... both drug addiction and sexual addiction represent pathological forms of neuroplasticity along with the emergence of aberrant behaviors involving a cascade of neurochemical changes mainly in the brain's rewarding circuitry.

Drugs of abuse induce neuroplasticity in the natural reward pathway, specifically the nucleus accumbens (NAc), thereby causing development and expression of addictive behavior. ... Together, these findings demonstrate that drugs of abuse and natural reward behaviors act on common molecular and cellular mechanisms of plasticity that control vulnerability to drug addiction, and that this increased vulnerability is mediated by ΔFosB and its downstream transcriptional targets. ... Sexual behavior is highly rewarding (Tenk et al., 2009), and sexual experience causes sensitized drug-related behaviors, including cross-sensitization to amphetamine (Amph)-induced locomotor activity (Bradley and Meisel, 2001; Pitchers et al., 2010a) and enhanced Amph reward (Pitchers et al., 2010a). Moreover, sexual experience induces neural plasticity in the NAc similar to that induced by psychostimulant exposure, including increased dendritic spine density (Meisel and Mullins, 2006; Pitchers et al., 2010a), altered glutamate receptor trafficking, and decreased synaptic strength in prefrontal cortex-responding NAc shell neurons (Pitchers et al., 2012). Finally, periods of abstinence from sexual experience were found to be critical for enhanced Amph reward, NAc spinogenesis (Pitchers et al., 2010a), and glutamate receptor trafficking (Pitchers et al., 2012). These findings suggest that natural and drug reward experiences share common mechanisms of neural plasticity

PMID 23430970. ΔFosB has been linked directly to several addiction-related behaviors ... Importantly, genetic or viral overexpression of ΔJunD, a dominant negative mutant of JunD which antagonizes ΔFosB- and other AP-1-mediated transcriptional activity, in the NAc or OFC blocks these key effects of drug exposure14,22–24. This indicates that ΔFosB is both necessary and sufficient for many of the changes wrought in the brain by chronic drug exposure. ΔFosB is also induced in D1-type NAc MSNs by chronic consumption of several natural rewards, including sucrose, high fat food, sex, wheel running, where it promotes that consumption14,26–30. This implicates ΔFosB in the regulation of natural rewards under normal conditions and perhaps during pathological addictive-like states.
