Men don't want women with high N-counts for a number of reasons.

One. They associate high N-counts with being a slut. Especially chicks with 20 sexual partners or more. No guy (except blue pillers) want to marry a "slut". It is what it is. That's how most guys feel.

Two. They want somebody with similar amounts of sexual experience as them. If they only had sex with 5 or 6 women, why would they want a woman that's been with 40 guys? Not even calling her a slut here but, in terms of sexual maturity, she's way beyond this dude. The way they view sex and relationships will likely not coincide. She will have likely done alot more sexually than he has and will not hold the same value on intimacy that he does. It wouldn't be fair to him. It would be the same way if a girl that was relatively chaste hooked up with a guy that screwed everything that moved.

Which brings me to my next point, why on Earth would you even want that as a high N-count person. They get so caught up on being shamed for their sexuality and being denied or discriminated against for a relationship because of their past that they never sit down and ask themselves why the hell they would want to be with someone who has a way lower N-count than them? Why would you want to have to hide your past? Why would you want to have to tell lies and hope your partner doesn't find out? Why would you want to be with someone who isn't on the same wavelength with you sexually or nowhere near you in terms of sexual experience. That discrepancy would rear it's ugly head throughout the relationship over and over again. Wouldn't it make sense to find someone who has a high N-count too? Equally yoked and all that sort of stuff. That way people with long sexual rap sheets don't have to lie and hide their past. And people who aren't as sexually experienced don't have to feel insecure about their partner's history. People who ride bikes with training wheels and knee pads should date and people who ride motorcycles with no helmets on should date. I don't understand why someone who's the former would even want a relationship with the latter.
