During the most recent revision of the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM-5), hypersexual disorder was proposed as a new diagnostic category. [1] The submission was ultimately rejected, but in the process a number of useful reviews relating to the assessment and treatment of hypersexual disorder were undertaken. [1-4] In the literature this condition has also been called compulsive sexual disorder, sexual addiction and non-paraphilic sexual disorder, reflecting different approaches to conceptualising its aetiology.
