Wikipedia
Odaxelagnia

Odaxelagnia is a paraphilia involving sexual arousal through biting, or being bitten. Odaxelagnia is considered a mild form of sadism. Alfred Kinsey studied Odaxelagnia, reporting that roughly half of all people surveyed had experienced sexual arousal from biting. Odaxelagnia has associations with vampire lifestyles, but does not necessarily involve bloodletting.
