Necrophilia is a term for the sexual attraction to corpses. Psychologists cite that in 68% of cases, the most common motive for necrophiliacs is a desire to control a partner who does not resist. It is classified as a paraphilia by the Diagnostic and Statistical Manual of the American Psychiatric Association. Necrophilia is believed to be rare. Even where it is exists, it is most often carried out in the form of fantasy or role-playing.
