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 embarassed,"responded Mary. "But after you go, will you tell me how it went?"

Several weeks later, at lunch Mary asked, "So, how did the sex therapy work out, Linda?"

"Things couldn't be better," Linda exclaimed.  "We bagan ith a physical exam, and afterward the doctor said he was certain he could help us.  He told us to stop at the grocery store on the way home and buy a bunch of grapes and a dozen donuts.  He told us to sit on the floor nude and toss the grapes and donuts at each other. Every grape that went into my vagina, John would have to get out with his tongue, and every donut that I ringed his penis with, I had to eat. Our sex life has been greater than it's ever been."

With that endorsement, Mary talked her husband into an appointment with the same sex therapist.  After the physical exams were completed, the doctor told Tom and Mary, "I'm afraid there's nothing I can do for you."

"But doctor," Mary complained, "You did such a great job for Linda and John, surely you must be able to help us.  Can you give us any help at all?"

"Well, OK," the doctor answered. "On your way home I want you to stop at a grocery store and buy a bag of apples and a box of Cherrios..."
