Hematolagnia

Blood fetishes are, obviously, commonly associated with vampire fetishes. It is not exclusive to those with a vampire fetish. Hematolagnia involves arousal by the physical presence of blood on a sexual partner, any erotic play with blood, bloodletting and biting, or licking and drinking of a partner's blood. The popularity of blood play has increased along with biting fetishes with the rise in popularity of films like Twilight and television shows like Vampire Diaries.
