The claim that masturbation isn t good for you didn t just come out of nowhere. As April Haynes shows, a range of feminist reformers in nineteenth century America all agreed that the solitary vice caused untold suffering and death; that women and girls masturbated as frequently as did men and boys; that they did so because they lacked access to sexual information; and that therefore, female sex education would save lives. Haynes, in short shows that nascent feminists remade what might have been a puritanical crusade into a basis for envisioning their own sexual self-masterywith mixed results, for Haynes also tells the story of how, before the advent of sexology or even the professionalization of medicine, a great silent army of evangelical female reformers first popularized, then institutionalized, the normative sexual discourse of the nineteenth century."
