Sexual cannibalism is considered to be a psychosexual disorder, which involves a person sexualizing the consumption of another person's flesh. This does not necessarily suggest that the cannibal achieves sexual gratification only in the act of consuming human flesh, but also may release sexual frustration or pent up anger. Sexual cannibalism is considered to be a form of sexual sadism and is often associated with the act of necrophilia (sex with corpses). There have been several high profile cases, which have involved sexual cannibalism, including that of Andrei Chikatilo, Edward Gein, Albert Fish, Armin Mewes and Jeffrey Dahmer.
