I think that sex is so abundant for women that most of them don't actually count all their sexual encounters as actual "sex". It is in such excess and so worthless to women that to itemize every encounter like men do would be absolutely pointless. Which is why many of them don't so much as lie about their N counts but do not consider most of their sexual encounters worthy of being an actual notch.

For most Men on the other hand sex is such a rare commodity that most men can tell you the first boob they have ever squeezed. You see it all the time in pop culture with men bragging and high fiving each other about the tiniest most minuscule sexual interactions with a woman that most women wouldn't even remember. Guys who bed multiple women are called "legends" among their male peer groups because it really is that difficult as a man to even just get a phone number let alone have a woman end up giving you head.

That's why N counts have such importance to men because for them it is a challenge it is an accomplishment for them because the dating game is rigged against them. So for them to get sex and an abundance of it shows they are winning when the odds are stacked out of their favor. And for women to have plentiful, large N counts it shows they are willing to take advantage of the current sexual marketplace. They are willing to cash in when the demand is high (which it always will be) and that scares men because they know how easy it is to get sex as a woman from an abundance of men.

Men don't want to constantly be on guard even more so then they already have to be. So a woman with a high N count is just an unnecessary headache. Most men do everything in their power to avoid unfaithful women so if they get indicators that a woman actively participates in and knows and takes advantage of the abundance of sexually available men they would rather not deal with it and date a woman who is either in the dark about it, doesn't value random hookups etc. .

And then women say "well we don't want sex we want relationships." Random hookups can't lead to relationships? If a long engaging conversation at a party can be the frame work for a new relationship why couldn't great sex be too? So if that's the case women having more access to sex then men means they also have more access to relationships too by proxy. That's another thing women don't understand. Most people want relationships and want to get married at some point so its disingenuous to act like men just want sex for sexes sake. Sex can lead to so much more. Which is why men are wary of women who participate in too much of it. They understand sexes value. They understand the value in validation from the opposite sex in any appreciable form because most men are so used to being ignored. Women are spoiled with attention and validation from every avenue.
