We're socialised to be sexually repressed.
Fortunately some of us aren't
Let's not forget biology! For most of human history, sex was a risk(ier) enterprise for women. It's only very, very recently that birth control (and norms fostering the use thereof) became widespread. Women ran the risk of pregnancy, and further, that the men who impregnated them might not support them financially at a time when there were much, much fewer daycares or a robust nanny service sector. Childbirth was also very dangerous, with (surprisingly) high rates of death for women. 'Slut-shaming'? Seems to me this was borne out of a culture that wanted to strongly suppress a woman's 'desire' because yielding to that desire had genuinely serious consequences.
