No doubt they have.

I have not claimed otherwise. I don't have to be an anthropologist to realize that different groups of people practice different customs and traditions, including sexual. But that has nothing to do with my commentary.

My comment was exposing the flaws in the claim that men invented "patriarchy" to gain unfettered sexual access to women, by making the obvious observation that men who live within this "patriarchy" don't have unfettered sexual access to women.

I don't see that you are disagreeing with my observation. Are you?
