"Since I heard your talk, I’ve sent your newsletter to several prospective girlfriends...just to test the water. None of them are too thrilled," said a discouraged male friend.
Alas, the prediction of J. William Lloyd in The Karezza Method  has not yet come to pass. Early last century he assured readers that as the Women’s Movement grew, Karezza (controlled intercourse) would come into its own:
The more frequently [orgasm] is employed, the more love dies, romance evaporates, and a mere sexuality, a matter-of-fact relation, or plain dislike, takes the place of the glamour of courtship days. …
As women learn [Karezza’s] transcendent importance to their happiness and health, they will demand it and refuse all men that cannot supply that demand. That will be a force that cannot be withstood.
