I'm not much of a sex talker, I'm not sex ninja or sex ghost either, I make noise but I rarely say full sentences.
But one time, I was super comfortable and I was with a fellow nerd. We talked about transformers earlier, no not the Michael Bay movies, So I said:
"ME GRIMLOCK ME KING!"
It worked very well as an amusing way to get things going.
So what's most amusing thing you've said in bed?
