Think back, for a moment, to the year 1968. Martin Luther King Jr. and Bobby Kennedy were assassinated. The Beatles released the “White Album.” North Vietnam launched the Tet offensive. And American women discovered the clitoris. O.K., that last one may be a bit of an overreach, but 1968 was when “The Myth of the Vaginal Orgasm,” a short essay by Anne Koedt, went that era’s version of viral. Jumping off of the Masters and Johnson bombshell that women who didn’t climax during intercourse could have multiple orgasms with a vibrator, Koedt called for replacing Freud’s fantasy of “mature” orgasm with women’s lived truth: It was all about the clitoris. That assertion single-handedly, as it were, made female self-love a political act, and claimed orgasm as a serious step to women’s overall emancipation. It also threatened many men, who feared obsolescence, or at the very least, loss of primacy. Norman Mailer, that famed phallocentrist, raged in his book “The Prisoner of Sex” against the emasculating “plenitude of orgasms” created by “that laboratory dildo, that vibrator!” (yet another reason, beyond the whole stabbing incident, to pity the man’s poor wives).
