A liberal myth.
A husband is having a hard time making his wife reach orgasm, so the couple goes to see a sex therapist to try to fix their problem.
The therapist says "Your wife may be too hot during sex to be comfortable. You should try having someone wave a towel over her to cool her down while you two are making love."
The husband asks a friend into the bedroom to help, and he agrees. The couple starts going at it while the friend waves a towel, but the wife still isn't having any luck. Frustrated, the husband asks the friend to have sex with his wife while he waives the towel. After just a few minutes, the wife has earth-shattering orgasm after orgasm. When it's finally over, the husband turns to his friend smugly and says, "Now THAT is how you wave a towel!"
