I guess what I mean by that probably came more from the female perspective.
It is natural because women invest way more into mating. Childbirth was a potential risk of death in human history. Bearing and nurturing children means your access to resources is both reduced while the need is increased.
Is vulnerability.
Monogamy secures you a partner that actually care for your wellbeing and for your offspring. One partner means less risk to get a sexual transmissible disease (killing millions in the past)
Female with monogamous tendencies survived better than promiscuous, so they passed on their genes.
But monogamy is natural for males too.
Yes we are more "predators" in the sense that even suboptimal females can be good for sex, is a way to pass on your genes, we do not risk pregnancy. But you do not stay with those. You want to stay with a partner who truly matters.
And when that's on the menu, you do not want to eat anything outside.
Again these traits were most successful because the committed couples lived longer (they still do today), were healthier (still valid today), had a more successful offspring (still verifiable today) so they have been selected for success.
The monogamous female does want a monogamous male.
The promiscuity is plan B for both. For men is obvious. For females was ensuring a backup in case the plan A failed or the plan A died. TO keep the offspring safe (of the plan A) they were ready to bounce to plan B if their partner died, so Plan B, C, D etc would take care of the offspring at the reward of having a female to reproduce (and they likely had a pull towards monogamy with her).
It is normal for guys to frack around until they commit to one. It is normal for girls to keep around male "friends" just in case.
When both find a stable relationship those behaviors are generally put aside. Unless in the cases of issues that we face here, promiscuity is forgotten until the union is stable, likely for the rest of the life (assuming no partner dies young).
If the couple was broken due to death or tragic incidents, then the surviving partner (male or female) returns to the backup behavior, isolation is not a good thing for human health and vitality.
But it will always try to secure another plan A, not indulge forever in the Plan B if the individual is healthy (emotionally mature).
So we have a bit of both, Promiscuity and monogamy, with the second being the most desirable for survival and thriving. We move through those stages, polygamy will always make you feel the need to pick one, is just too expensive to be sustainable as a relationship matrix.
Cheating in this scenario, simply brings the plan B before the plan A, breaks the plan A, betrayal reduces livelihood, life expectancy and survival chances.
That's why it is painful. For both, as the Wayward often realizes soon or later that they messed up plan A for plan B and now it's hard to get back there.
Is nt only females who care the most hiking, males care for it too, is just different approaches but we both crave the same.
