All of this is true, given that we are living in an unnatural state.

However, what we have forgotten, or chosen to ignore, is that men and women are supposed to live separately. Women form the main community, gather some food, grow some crops, make things, raise kids. The men live on the periphery, take in the male kids as soon as they are mobile enough. Half of them are out hunting at any given time while the rest are standing guard.

Interaction between the sexes is supposed to be strictly transactional. Men share the kill or perform heavy labour when needed in return for produce as well as keeping the men of other groups away.

Men would tend to die more because what they do leads to more injuries and back then, almost any injury was fatal.

In early winter, all the women who feel able and the men who have proved themselves make camp together and fornicate for a month or so. This is so the babies will be born toward late summer when food is more plentiful. For the rest of the time, you have sex with your own gender.

Whichever idiot first decided that men and women should live together in a shared space has caused everyone no end of trouble!
