Erotophonophilia

Erotophonophilia is a paraphilia (unusual sexual interest or attraction) that centres on the act (real or imagined) of committing murder; it is the most extreme form of sexual sadism. Erotophonophiliacs tend to fantasize about beating, stabbing, strangling and mutilating their victim(s); they also engage in idealized narcissistic fantasies of domination and utter control over their victim(s). Murders committed by erotophonophiliacs are often marked by genital mutilation or dismemberment, and disembowelment. Erotophonophiliacs are more likely to be primary psychopaths than non-erotophonophiliacs, more likely to engage in cruelty to animals, and also more likely to become serial murderers. They are more likely than other murderers to engage in cannibalism, torture and 'trophy keeping'.

This paraphilia finds its counterpart in autoassassinophilia, where the person derives sexual satisfaction through their real or imagined death through murder.
