Sex positivity shames those, primarily women, who do not want to engage in kinky sex, those who have a lower sex drive, and those who have been cheated on. I have no idea how anyone could buy the lie that it is pro-woman or pro-anyone, really.
Sex positivity seems like the sexual revolution on steroids. Once the Pill came out and rendered sex a pleasurable moment without context, women no longer had an excuse to refrain.
Now women are socially pressured to engage in kinky sex.
Qui bono? Not women. And “liberating” women more won’t help.
