Tennis Porn

I went to the barber shop today to get mine and Q's mop chopped. While I was there they had the Wimbledon Championships on and I swear if I wasn't looking at the TV it would have sounded like lesbian porn the way the ladies where grunting and moaning. I watched one women's match and the start of a men's match where there was no grunting or moaning. I know that during sporting matches you're bound to make noise of exhaustion, I've done it my self. It was made worse because of the stadium being so quiet. The question still remains; why are the guys quiet?
