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."
