Weird but true. I'm all for hand cuffs, hair puling, biting, anything that hurts, works. If it's not rough it isn't fun
I've never told anyone to stop no matter how bad it hurt. Pain and pleasure are exactly the same in my mind. Most chicks would be pissed if their man slapped them in the face, but I'd prolly just jump him right there. I'm a bit fucked up.
