Unlimited access to unlimited sexuality is what the male sexual strategy is. Men throughout history were Polygynous by nature, saying that polygyny is not the natural state of man is just false, disingenuous and just shows how out of touch you are with reality.
Men desire sexual abundance but not every man can afford that.
we are Polygynous by nature but monogamous by necessity.
just did research, turns out @Shimbiris is right. All papers show that our HG ancestors were indeed monogamous. TBH, even our religious traditions illustrates that with with Adam and Eve and the earlier generations of mankind all marrying one woman. According to science, polygamy only comes about during the advent of agriculture and private property. Once men enter agricultural way of living and start the concept of private property and with that warring over property did humans start having multiple wives.
