About 50%, I also watch gangbang porn a lot. I want to be the chick with all those dicks in her.
I don't want rape porn to be TOO realistic. I would feel guilty about the possibility that I was getting off on some other girl being ACTUALLY raped. I just want it to be realistic enough for the fantasy. My fantasies aren't really about abuse or humiliation--they're about being overpowered and overwhelmed and surrounded, and situations where I didn't expect/want it add an extra charge.
