Compulsive sexual behaviour disorder

Compulsive sexual behaviour disorder (CSBD), is a psychiatric disorder which manifests as a pattern of behavior involving intense preoccupation with sexual fantasies and behaviours that cause significant levels of mental distress, cannot be voluntarily curtailed, and risk or cause harm to oneself or others. This disorder can also cause impairment in social, occupational, personal, or other important functions. CSBD is not an addiction, and is typically used to describe behaviour, rather than "sexual addiction".

CSBD is recognised by the World Health Organization (WHO) as an impulse-control disorder in the ICD-11. In contrast, the American Psychiatric Association's (APA) DSM-5 does not recognise CSBD as a standalone diagnosis. CSBD was proposed as a diagnosis for inclusion in the DSM-5 in 2010, but was ultimately rejected.

Sexual behaviours such as chemsex and paraphilias are closely related with CSBD and frequently co-occur along with it. Mental distress entirely related to moral judgments and disapproval about sexual impulses, urges, or behaviours is not sufficient to diagnose CSBD. A study conducted in 42 countries found that almost 5% of people may be at high risk of CSBD, but only 14% of them have sought treatment. The study also highlighted the need for more inclusive research and culturally-sensitive treatment options for CSBD.
