thats a bit too general for me
i gave an example of my father's people which would seem to conform to your ideas
but i can also give other examples from my country and kenya where this is not the case
for example i can give you my mother's people as an example
where we mostly form monogomous relationships that are on a more or less equal basis
yes there are still fixed roles/notions of gender
but men still be hand holding and loving each other and their women
so i dont see it as x causes y
