This is fascinating! (I have got to get around to writing up the book I read recently about Paschal Beverly Randolph -- " A Nineteenth-Century Black American Spiritualist, Rosicrucian, and Sex Magician" -- which chronicles in great detail his journey from believing that sex is only correct and powerful-in-an-occult-way when nobody orgasms to believing that sex is only correct and powerful-in-an-occult-way when everybody orgasms.)
