Once a cheat, always a cheat = If someone makes that choice once, they’ll make it again.
Behavioural genetics is confirming what the traditionalists already knew.
As for the neurochemistry of vasopressin, low levels of any count as pathological (see depression, OCD etc).
If the K-types wanted a surer mating game in future, a simple genetics test to distinguish the short allele (K-selected, monogamous) types from the deceptive hedons with a long-form allele (r-selected, high infidelity risk) would cut the latter off at the heels. It isn’t an excuse, but again, if they make that choice once, they’re tainted and should be divorced.
Imagine short-listing the prospects for your daughter’s hand, and your grandchildren’s genetics, based on this, oh the wonders of technology! Simply cutting them out from social circles would be a genetic death. Why do you think slutty people congregate in urban areas, where nobody knows them and they’d have to be dismal to build a reputation among their own? Why do you think we collect alcoholism, drug and sexual information as a bundle?
This isn’t just a marital issue, it covers social deception, this is just one sexual application of it i.e. K-selected males would be unwise to accept an r-male into their group, because he’ll screw you over metaphorically. And you shouldn’t leave him with a free house (some stay-at-home fathers) because he’ll invite over your wife too.
Most sperm are destroyed by white blood cells. However, here’s a horrifying fact about where it can escape;
“Once sperm cells reach the end of the oviducts they are free to swim out of the end of the tube and into the body cavity, where they are eventually destroyed. So many women walking around today will have sperm cells swimming around the interstitial fluid that surrounds their body organs. The female reproductive tract does not finish in a dead end.”
