A case is described of female compulsive sexual behaviour in association with obsessive-compulsive disorder (OCD). This patient had non-paraphitic compulsive heterosexual multiple partner behaviour, which is a symptom complex previously termed nymphomania. There were also nonsexual obsessions, compulsions and avoidance behaviours diagnostic of obsessive-compulsive disorder. The case is presented for its clinical interest, because ‘nymphomania’ is rare, and because the patient presented with symptoms subtly different to others in the literature. The patient consented to her case being reported in the medical literature.
