Isn’t the idea that women are uninterested in sex compared to men a fairly modern (I want to say 19th-century, but I’m not sure) invention, presenting them as “pure” and innocent and needing to be sheltered? If I remember correctly, in Medieval times, for example, it was taken as a given that women were more horny and prone to adultery than men, due to Eve’s sin or something along those lines.
(The reality, I think, is that men and women are about equally interested in sex, though how that manifests is obviously affected by cultural expectations and, possibly, by actual sex-based differences… though I wouldn’t be surprised if those turned out to be an insignificant factor.)
