some people drink others' blood.
Yeah a girl that grew up down the street from me had a boyfriend (well she had several "boyfriends") that thought he was a vampire and would drink her blood lol. She was a major slut, slept with tons of guys I know. I could have had her but I rejected her actually, made out with her at the bus stop several times. She would fuck guys for drugs haha. She would show me the marks he left and tell me about how fucking stupid this guy was, she was pretty dumb herself. Her brother got in a wreck and killed someone while drunk. Good times.
I have tasted my own blood many times, but I don't cut my arm or anything. I punch myself in the face though and blunt force trauma is pretty crucial. I started that when I was 15 I think. I actually have known one other person who would punch himself in the face when he was angry with himself (was in HS with me). That can get you bleeding in the mouth pretty damn good, plenty of bloody noses as well. Busted lips are common along with some good bruises (broke my braces many times). I would say blood tastes pretty damn good to be honest, kind of salty (well its Iron). I don't know if I would get sick from actually drinking a good deal of it. Punching a brick walls, trees and such gets me some bloody knuckles at times, but I don't lick or taste my knuckles bleeding. I haven't done that in a long time actually.
I also bite my tongue to stay awake when driving long distances, but that has only drawn blood a few times. That was pretty damn crazy to be honest, driving at 90+ mph on I-95 driving back from Tampa from seeing Morbid Angel, Vader and Incantation all fucked up on booze and weed (drinking Mountain Dew to stay awake). Trying to stay awake and bit the living shit out of my tongue to do so (caffine wasn't working sadly as usual). Ended getting a good mouthful of blood, was pretty damn hard to stop bleeding. Had to use one of my hands and was quite messy. My friends were all asleep haha.
I can see the appeal of cutting, but I really love the pureness of blunt force. When I hit that ecstacy dealer (the one who sold the dirty pills) with a tire iron for example, it was fucking awesome how his skull cracked with this sickening noise. I honestly could have masturbated to the feeling I felt. He was out before he hit the ground face first. If I had to kill someone I really hated, it would have to be via blunt force. Just seems more passionate and probably satisfying that way, bloody skull fragments and all.
