The term "Orgasm Vampire" refers to someone who gets off on your orgasm.
Sort of like stealing someone else’s high.
An Orgasm Vampire won’t stop until you:
A) Have an orgasm or multiple orgasms (whether you want to or not).
B) Fake an orgasm, so they’ll stop pounding you.
C) Expire. (Die)
D) Call your girlfriends and invite them over.
E) Have to go to church.
Rapists and child molesters are also Orgasm Vampires.
Married men/women can also be Orgasm Vampires because it is not enough that they have sex at home they go prowling, looking for it elsewhere. Sort of like a sexaholic.
