Most men’s ideal romantic situation is to enjoy a variety of consecutive relationships. Why can’t women today accept to share their men? Our fathers and grandfathers managed their many partnerships successfully.
No, our fathers, grandfathers, and great-grandfathers were not successful at it. They owned all the property there was to hold, and in most cultures, that included women and children. They could have a polygamous lifestyle because women had no means with which to challenge them. They beat those who tried into total submission and subservience. That was not successful management of multiple partners. It was tyranny. Without much choice, the womenfolk fell in line. It wasn’t acceptance of the situation.
