When I'm around someone with pale or soft-looking skin, I;ll always have a sudden impulse or more of a desire, really, to bite their neck. Not to kill them, just drink their blood, only a little bit. Yes, I am a big fan of twilight, but I'm not some vampire-wanna-be, I plainly have the instincts and impulses to drink people's blood, or have crazy ideas about stealing blood from hospitals and drinking it...Is this normal? Or can you relate to it?

Biting whilst having kinky sex-normal.
Wanting to drink blood and even thinking about stealing blood supplies from hospitals which seriously ill people will need- er, certainly not normal.
I just solved it...
