This guy goes into a doctors and says "Doctor, doctor you've gotta help me. I just can't stop having sex!" "Well how often do you have it?" the doctor asks. "Well, twice a day I have sex with my wife, TWICE a day", he answers back. "That's not so much", says the doctor. "Yes, but thats not all. Twice a day I have sex with my secretary, TWICE a day," replies the man. "Well that is probably a bit excessive," says the doctor. "Yes, but thats not all. Twice a day I have sex with a prostitute, TWICE a day," says the man. "Well, that's definitely to much", says the doctor. "You've got to learn to take yourself in hand." "I do", says the man. "Twice a day."
