Sexologist Shere Hite wrote one of the best-selling books of all time, The Hite Report; transformed the lives of millions of people through her eye-opening findings about the female orgasm; then vanished from public awareness in the course of a mere 50 years. That, at least, is the argument of a new book by the London-based academic Rosa Campbell, The Book That Taught the World to Orgasm and Then Disappeared, as well as a 2023 Dakota Johnson–narrated documentary, The Disappearance of Shere Hite. The framing of both these works is tricky; to say that no one talks about or remembers a thinker of the relatively recent past is a fuzzy practice, as it depends entirely on who you know and talk to. I happen to remember Hite and her books quite well, but Campbell—who appears to be younger than I am—maintains that when she told her colleagues and friends that she planned to write about Shere Hite, she got nothing but blank looks in response, and we’ll have to trust her on that.
