Showtime’s acclaimed series Masters of Sex comes back for its second season this weekend, but before it was a hit show, the real Virginia Johnson and Dr. William Masters graced the May 25, 1970 cover of TIME to talk about their groundbreaking adult sexual education.
"The greatest form of sex education," Masters once said, "is Pop walking past Mom in the kitchen and patting her on the fanny, and Mom obviously liking it. The kids take a look at this action and think, 'Boy, that's for me!'"
While sexual myths of penis size and libido boosters still exist today, Masters and Johnson were the original debunkers. This is what their research concluded in the 70's.
1. Penis size has nothing to do with sexual effectiveness.
2. Baldness is not a sign of virility.
3. There is no physiological difference, as Freud first proposed, between a clitoral orgasm and a vaginal orgasm.
4. Humans can remain sexually active well into their ninth decade. “All that is necessary,” says Masters, “is reasonably good health and an interested and interesting partner.”
5. Intercourse is not dangerous at any time during pregnancy—unless, says Masters, it is contraindicated by “ruptured membranes, pain and bleeding.”
6. Masturbation is not harmful.
