So the other night I was going down on a girl and she had what I guess was a pretty intense orgasm. She kind of just lay there and didn't say anything for a while which has been the norm for me, then said "Fuck you" and "how do you know how to do that?"...and then said fuck you a couple more times and went to the bathroom. For some reason, it was a huge turn on. Any women do this, and if so, why?
