The terrible mystery of humanity has been uncovered. All humans are polygamous by nature, not "masculines". Both genders. For primates, this is evolutionally beneficial. Moreover, polygamy is not in “being on the right-left side”, but in the fact that if the partner died or broke up with him, then you can find a new partner, and not keep the labyrinth loyalty, widowed at twenty-five years and lived to eighty.
Changing one partner for another if the other is more suitable is a manifestation of polygamy. Fucking all his friends behind a partner’s back is a manifestation of ordinary hypocrisy. From the notorious nature, both can be equally inherent in both sexes, just women are less inherent in CULTURE, girls are raised stricter in this matter, hence the myth of female non-polygamy.
