A concerned patient asked the doctor if masturbation was harmful.
“Not usually,” answered the doctor. “Not unless you do it too often.”
“How about three times a day?” the patient asked.
“That seems a little excessive,” the doctor muttered. “Why don’t you get a girlfriend?”
“I already have a girlfriend,” the patient replied.
“I meant a girl you can live with and have sex with.” explained the doctor.
The patient replied, “I got one just like that!”
Puzzled, the doctor asked, “Then why do you masturbate three times a day?”
The patient explained, “Because she won’t have sex during mealtime!”
