"Wallen, like Masters and Johnson, thinks it's possible that a majority of the so-called vaginal orgasms being had during intercourse are in reality clitoral orgasms. But unlike Masters and Johnson, he doesn't suggest that most women are having them easily. He believes, like Bonaparte, that the women having them--the paraclitoridiennes of the world--are an anatomically distinct group whose sexual response is different from that of the majority of women. And that maybe these women are "where the whole notion of the vaginal orgasm originally came from."
