Edit: Damn autocorrect. Title should say "Widow" not "window"
I posted this as an answer to a comment elsewhere but I don't know if I've ever written about it. The "Insatiable Alpha Widow"
The reason you want to avoid women with high body counts, and older (always single) women.
The higher the body count, the more likely she's alpha widowed (i.e. all subsequent partners are overshadowed by 'the one' who broke her tingle meter).
But, as the number grows and she ages, she reaches a state I call the "Insatiable Alpha Widow." Like an alpha widow on steroids.
So here's the theory:
Women tend to be hypergamous, that is, their goal is to get the highest quality partners they can. The easiest way to measure "higher quality" is by comparing mates to each other.
First guy makes a little cash, drives a beater. Second guy drives a Bugatti. Second guy wins.
First guy is strong, second guy has abs. Second guy wins.
First guy has a good sense of humor, second guy is locally famous and everybody knows him. Second guy wins.
And so on.
Women like men who are better than other men. This should not be a surprise to you.
Well, over the years, women might date a lot of guys. Some buff, some rich, some charming, etc.
Eventually over time, she will start comparing new men, not to a single previous partner, but instead, to all partners.
She dated a rich guy, a funny guy, a strong guy, and now if you don't compete in all 3 categories, then she thinks she can do better. And she has done better... just not in one guy.
But for her, that doesn't matter. She is now subconsciously comparing you to multiple guys and will be disappointed when you don't rock her the way each one did.
The strong guy was better at sex. The funny guy had a better sense of humor, etc.
She has been alpha widowed. But not by one guy. By all the guys.

This leads to the thousand-cock stare, but is also why women in their late 30s+ tend to be more independent and less likely to settle down (unless it's to a beta bucks). They can no longer get the tingles from any particular guy except maybe a super hero but her chances to land one diminish as she speeds well past the wall.
Eventually, at a particular age, she will either settle into an unhappy marriage, or rationalize why she's happier alone.
But she will never be truly happy with any mere mortal again.
