A young couple left the sex therapist’s office determined to develop more effective body language.

“Alright,” said the husband, “when I want sex, I’ll rub your right breast. When I don’t want sex, I’ll rub your left breast.”

“Okay,” said the wife, “What should I do then?”

“Well, when you want to have sex,” he told her, “rub my penis once. When you don’t want any sex, rub it 200 times.”
