Please don't ban me, I'm not trolling here.
Basically, a few weeks ago I was having sex with a girl and I'd heard dirty talk really gets them turned on. It was really a casual thing, since she has a boyfriend out of state who apparently isn't very sexually oriented, so I decided to give it my all on that particular occasion. This girl was into all sorts of nasties, such as tying my hands to the bed with my drinking soc tie, a little mild spanking and even sex on a couch. So I thought using a bit of dirty talk would be right up her street. I cried out "you slut" (or maybe I said “slag". since that's the term I use more often, but it doesn't really translate here) and spanked her, and she told me to f off if that's how I felt.
Since then I've bumped into her a few times in the hallway and she's just blanked me. She seems more pissed off than hurt, but why? What's the difference between a little role play with ties and corsets and stuff and some sexual banter while doing the act? I thought it would go nicely with the slightly more kinky experiences we'd been having. My friends are saying it is fine and a bit of a turn on, and I've seen it done in loads of pornos. Do you think such pillow talk is acceptable, and if you were a girl and the same was said to you, would you be turned on or offended?
