This guy visits the doctors and says, "Doc, I think I've got a sex problem. I can't get it up for my wife anymore." The doctor says, "Come back tomorrow and bring her with you." The next day, the guy shows up with his wife. The doctor says to the wife, "Take off your clothes and lie on the table." She does it, and the doctor walks around the table a few times looking her up and down. He pulls the guy to the side and says, "You're fine. She doesn't give me a hard-on, either."
