Sexual addiction

Sexual addiction is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences. The concept is contentious; as of 2023,^[update] sexual addiction is not a clinical diagnosis in either the DSM or ICD medical classifications of diseases and medical disorders, the latter of which instead classifying such behaviors as a part of compulsive sexual behavior disorder (CSBD).

There is considerable debate among psychiatrists, psychologists, sexologists, and other specialists whether compulsive sexual behavior constitutes an addiction – in this instance a behavioral addiction – and therefore its classification and possible diagnosis. Animal research has established that compulsive sexual behavior arises from the same transcriptional and epigenetic mechanisms that mediate drug addiction in laboratory animals. Some argue that applying such concepts to normal behaviors such as sex can be problematic, and suggest that applying medical models such as addiction to human sexuality can serve to pathologise normal behavior and cause harm.

None of the official diagnostic classification frameworks list "sexual addiction" as a distinct disorder.

Proponents of a diagnostic model for sexual addiction consider it to be one of several sex-related disorders within hypersexual disorder. The term sexual dependence is also used to refer to people who report being unable to control their sexual urges, behaviors, or thoughts. Related or synonymous models of pathological sexual behavior include hypersexuality (nymphomania and satyriasis), erotomania, Don Juanism, and paraphilia-related disorders.

The ICD-11 created a new condition classification, compulsive sexual behavior disorder, to cover "a persistent pattern of failure to control intense, repetitive sexual impulses or urges resulting in repetitive sexual behaviour". However, CSBD is not considered to be an addiction, and the WHO does not support a diagnosis of sex addiction.

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

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." The reference to sexual addiction was subsequently removed. The DSM-IV-TR, published in 2000 (DSM-IV-TR), did not include sexual addiction as a mental disorder.

Some authors suggested that sexual addiction should be re-introduced into the DSM system; however, sexual addiction was rejected for inclusion in the DSM-5, which was published in 2013. 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." According to the APA, the proposed diagnosis was not included due to a lack of research into diagnostic criteria for compulsive sexual behavior.
