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. In clinical diagnostics, the term 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. Clinicians, such as psychiatrists, sociologists, sexologists, and other specialists, have differing opinions on the classification and clinical diagnosis of sexual addiction. As a result, “sexual addiction” does not exist as a clinical entity in either the DSM or ICD medical classifications of diseases and medical disorders.
