I'm not really sure where this dogma came from that monogamy is a modern invention. Humans are both monogamous and polygamous, depending on their environmental demands and opportunities. Pair bonding is certainly nothing new on a historical scale; marriage notwithstanding.
My whole point was that it is a natural repulsion when a man is turned off by a perceived (or known) slvt. Of course, what constitutes a slvt is debatable, but for the sake of argument we'll say a woman with more than 10 lifetime partners. It make perfect biological sense that we would be less interested in pair bonding with a woman who has had dozens of other men's DNA inside her. Higher likelihood of cuckoldry and questionable parentage, and higher likelihood of pathogen transmission. Additionally, a higher likelihood of sexual deviance in a monogamous bond. She has a known history of squandering a finite resource (her eggs).
From a monogamy standpoint there is
actual data that supports higher sexual partner counts
for the female result in markedly higher rates of marital dissolution. Marriage, for better or worse, is legally sanctioned pair bonding.
This is really kind of a big academic circle jerk, but from a purely reproductive standpoint, women desire superior genetics, while men desire superior fertility and verifiable parentage. It does not benefit an individual male to raise another male's progeny. Sure you could go into group/tribal dynamics and community child rearing, but a male primate's main reproductive imperative is to ensure HIS genetic offspring are as healthy and viable as possible. Sure we may have urges to
mate with various females, but NOT to invest our resources in the village cvm receptacle.
I really think that there is a phenomenon of modern men (even "red pill" men) mentally "neutralizing" the negative value of a slvt because that's all they think they can get. If you live in an orchard full of sh!tty brown apples, you start to think they aren't that bad after all. The brown apples are really ok, because x,y,z. But then when you DO find a pristine, delicious,
ripe apple, you realize you've been deluding yourself, and you wont ever go back.
