Autovampirism

Medical condition

Auto-vampirism is a form of vampirism that refers to drinking one's own blood, typically as a form of sexual gratification. As a mental disorder, this is also called as autohemophagia, which is derived from three Greek words: auto, which means "self"; hemo, for "blood"; and, phag, meaning "to eat". Although closely related to vampirism, the two differ in that vampirism is a sadistic act while auto-vampirism is on the side of masochism. Along with drinking their own blood, most practitioners of auto-vampirism also engage in self-harm in order to obtain the blood.
