An old man marries a young woman, and though they’re in love, the wife can’t achieve an orgasm.

They ask a psychiatrist for advice. He says, “Hire a strapping young man. While you’re making love, have him wave a towel over your bodies.”

The couple’s desperate, so they hire a male escort to wave a towel. But despite a lengthy lovemaking session, the wife still can’t get off. Willing to try anything, the husband and the strapping young stallion switch positions.

The guy goes to work, and the wife quickly has an earthshaking orgasm.

The husband smiles and says triumphantly, “You see, young fella? That’s how you wave a towel!”
