The OP asked a serious question and you try to make a joke out of it.  You also continue to demonstrate your sexual ignorance - simply because a man is interested in pegging and you're not does not give you license to make fun of him.

 
How would you like it if people made fun of you for trying to communicate with your cut-rate K-girls by using hand gestures or pidgin English?  Is this how a K-monger asks a K-girl for a BJ, lol:
