There's a poll/thread about this in the ladies lounge I remember seeing. Hey, even I get curious to see what in the hell those darn ladies talk about in their own forum. Unfortunately sometimes I would've been much happier not seeing or thinking about certain threads, but it does sometimes have some interesting stuff. Such as, the answer to this question!
"Have you ever faked an orgasm?"
Obviously males like me can't post there, but you can read the ladies' response to pretty much the identical question.
