Erotophonophilia is the sexual arousal deriven from murder. While, in some cases, this fetish never goes beyond the fantasy level, or possibly the roleplaying stage, this fetish is classified as a psychological disorder, and can be dangerous if the fantasy is taken too far, or if the subject begins to consider the possibility of carrying out their desires.

Often, the subject harbors fantasies about killing a specific person, (the object of their lust,) and is often known to be designed as a slow, deliberate murder. It is common for the fantasy to include mutilation of the body after the death. Commonly this type of crime is manifested either by murder during sexual intercourse and/or by mutilating the sexual organs or areas of the victim's body. The mutilation of the victim may include evisceration and/or displacement of the genitalia.

Because the nature of sexual philias and fetishes is to 'get to the next step', and to evolve one's fantasies into reality; any person who harbors a sexual desire to commit murder may become a risk, and should seek psychoanalysis immediately to be on the safe side.
