Sexual addiction, also known as sex addiction, is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences. Proponents of a diagnostic model for sexual addiction, as defined here, consider it to be one of several sex-related disorders within an umbrella concept known as 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 models of pathological sexual behavior include hypersexuality (nymphomania and satyriasis), erotomania, Don Juanism (or Don Juanitaism), and paraphilia-related disorders.
The concept of sexual addiction is contentious. There is considerable debate amongst psychiatrists, psychologists, sexologists, and other specialists over the whether compulsive sexual behavior consitutes an addiction, and therefore its classification and possible diagnosis. As of 2017, sexual addiction is not a clinical diagnosis in either the DSM or ICD medical classifications of diseases and medical disorders. 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.
