Compulsive sexual behaviour disorder

Compulsive sexual behaviour disorder (CSBD), is an impulse control disorder. CSBD manifests as a pattern of behavior involving intense preoccupation with sexual fantasies and behaviours that cause significant levels of psychological distress, are inappropriately used to cope with stress, 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 recognised by the World Health Organization as an impulse control disorder, and is categorised as "Compulsive Sexual Behaviour Disorder" in the ICD-11. CSBD is not categorised as a standalone diagnosis by the American Psychiatric Association in their DSM-5; it was proposed for inclusion in 2010, but was ultimately not approved.

Abnormal sexual behaviours such as chemsex and paraphilias are closely related with CSBD and frequently co-occur along with it. Psychological 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.
