If money is a bad expectation from a relationship why is sex ok to expect.

If expecting a man to be financially stable enough to care for his wife and child is considered too much. Why then is expecting sex from a relationship, where males almost always orgasm from piv and women almost always don’t, ok? Sex (piv) like financially taking care of your woman, should be optional. Just as it’s ok in society for a man to break up if he were no longer attracted to/she couldn’t have kids/she didn’t like piv etc. a woman should have the societal backing for her own standards. Especially considering statistically women still cook, clean, take care of the kids etc., all while having piv sex they never cum from (without other stimuli) AND they pay half, if not more than half the bills. Seems like feminism is actually for men 😂
