It's literally the first rule of life. Doesn't change that a hundred women is hard r-type behavior, that women lose the ability to pair-bond the more sexual partners they have
Men too - even more, perhaps.
This is speculation mostly from observation, but it seems like men are actually hurt by too little sex while women are from too much of it. Comes back to evolution, in tribal times the men who could get the most and the youngest women were on top of the social hierarchy. Women meanwhile wanted said top men, and not the other twenty losers in the tribe. Needs more research for anything definite tho.
and that it is how people in a declining culture behave.
I'd like it if we all declined some more.
We will.
