Hombre, what do you think your standards of beauty are? Why do you think you find facial symmetry, high hip to waist ratios, long necks, high cheekbones, breasts etc to be beautiful? And what do you think you use to gauge whether to sleep with someone?
All those criteria are things you use to gauge whether someone has good genes. That is why you consider them beautiful.
So yeah, everyone uses genetic match as the prime criteria for selecting sex partners. Maybe we use others as well after we get to know someone, but if we don’t find them physically attractive we probably won’t make much effort to get to know them.
The people we are most sexually attracted to are, almost by definition, the ones who are the best genetically.
And those things don’t change no matter what the medical standards of the day. Our standards of beauty are in large part a means of judging how well someone has survived in the environment we are currently living in. That’s because that is the environment the offspring will also nee dot survive in. Whether that environment contains antibiotics and laser surgery or contains smallpox and sabre=toothed tigers doesn’t matter. All that matters is whether the person has survived well within that environment.
Let’s make it quite clear: this woman is a child molester.
The fact that there may be instincts that make 14yos attractive doesn’t make it right to act on that attarction. Our instincts regularly urge us to beat the shit out of people too, we don’t act on them, and we don’t excuse people who do act.
Instinctive =/= moral.
Having said that, it’s impossible to sort out why people find other people attractive. There are the usual reasons like physical beauty, intelligence, social positiun and wealth. But then there are unlimited factors that aren’t obvious.
Most selection is done entirely subconsciously. This woman almost certainly didn’t say “My, I wnat to have a child with that boy”. But then almost nobody does that, ever. Our sexual desires are mostly subconscious and we certainly don’t know what prompted them. Because of that it mkaes little sense to say that there were other sperm donors available. This woman wasn’t consciously searching for a sperm donor any more than she would have been if she picked up some stranger in a bar.
Did she enjoy the aspect of control? Quite possibly. Does she have mental problems? Almost certainly given that she repeatedly committed serious illegal acts. But none of that detracts from the underlying point. The desire in itself isn’t some sort of defect. The defect was acting on it as she did. Just as desire for wealth or rich foods aren’t defects, but acting on those desires often can be.
No deep and complex psyhcological explanation is required for why she wanted to have sex with this boy. That can be explained by simple sexual selection instincts. The only explanation required is why she decided to act on it given the consequences for everyone involved.
And even those consequences are probably primarily cultural. In many, if not most, societies thorughout human history it was normal or even required that the first sexual contact that a pubecsent boy had was with a woman in her 20s or 30s. So the idea that women simply never have such desires is probably a cultural artefact with no biological basis.
The same applies to men who are attacted to teenage girls. Throughout our history the ideal mate for a man would have been a girl with the physical maturity equivalent to a modern 15yo. As such men are pre-programmed to find such girls attractive. But in our society girls mature earlier, and we don’t accept men having sex with 15 or 16 year olds. It’s a crime, and so it should be. But that doesn’t mean the desire in itself is wrong or unnatural or requires some psyhcological explanation. What is wrong is acting on the desire.
The idea that a 25yo being attracted to a 14yo who is physically identical to an 180yo is somehow unnatural or icky makes no real sense. It suggests he shouldn’t be attrscted to the 18yo either, which just ain’t gonna happen.
