Sexual Freedom
Sexual freedom is not actually freedom TO (do xyz).
We are always sexually free TO do whatever we want.
That's why there's cheating, and why monogamy cannot prevent cheating, why in fact monogamy is what creates cheating.
Monogamy is the context of promises and agreements which has us categorize some sex as right and some sex as wrong, or "cheating."
Without this construct, we have the sex we have with the people we have sex with.
Sexual freedom is freedom FROM.
