Two women had been having a friendly lunch when the subject turned to sex. "You know, John and I have been having some sexual problems", Linda told her friend. "That's amazing!" Mary replied, "So have Tom and I. We're thinking of going to a sex therapist", said Linda. "Oh, we could never do that! We'd be too embarrassed!", responded Mary. "But after you go, will you please tell me how it went?"

Every donut that I ringed his penis with, I had to eat. Our sex life is wonderful, in fact it's better than it's ever been!"

Please, please, can't you give us some help? Any help at all?" "Well, OK," the doctor answered.
