I hate hair pullin!

I'm a dude, with fairly long hair. It's a rich brown color, messy but still soft n' clean, n' my bangs are parted in the "curtain" fashion. More to the point, I consider myself a bit of a masochist, and I do get turned on when I'm dominated. I also get hit occasionally by girls that are my friends and don't do nothin bout it. HOWEVER, the one thing that can turn my happy-go-lucky, careless n' freelovin attitude sour, is when my hair gets pulled. I love gettin my hair petted, stroked, ect.; but I go from nice to grippin your wrists like vice if ya pull it. It doesn't hurt neither, least not usually, but I just snap anytime my hair is pulled, or if someone tries to cut it or somethin like that. I've punched a dude in the face for coming towards me with scissors even though he was jokin, and the worst I've ever done to a girl is knocked her down(granted, she was tryin to get in a fight with me and I wouldn't do anythin no matter how much she hit me). Usually it's girls who do it though, and I just grab your arm till ya let go and give ya a warnin. Sometimes I'll even stop bein ya friend just cuz ya pulled my hair and thought it was funny. I almost never handle it in an aggressive manner though, unless your a dude of course, then I'll knock ya f*ck'n lights out. So now I ask ya, is this normal?
