Why do men always have a problem with women’s body count
Because cuckoldry is to men what rape is to women.
It's like asking why women have a problem with rape. If I was alone in the woods and a random woman shoved her tits in my face I wouldn't find that traumatizing.
Also, women don’t even care about men’s body count or sexual history
Yes they do, they just go the other way. Women find virgin men gross. You can see this in how they argue and insult. When they want to put a man down, they compare him to a virgin because women think virgin men are disgusting. If a man abuses his GF, they call him a virgin even though he obviously isn't one, because they find being a virgin more offputing than being an abuser. When you call people names you always call them something worse than they actually are. Nobody calls actual mentally handicapped people "retards", the call normal people retards when they fail to meet the intellectual standards expected of normal people. Virgin, incel etc being the go-to insult for women shows that women think this is the worst possible thing a man can be, which proves that women do in fact care about men's body count.
Women’s body count lives rent-free in every incel’s head.
It's the opposite. Women are the ones who are insecure about it, which is why they constantly try to mock men for their preferences.and expect them to justify it. If your sexual history is so different from mine that I can't relate to you then I don't find you attractive. That's it. I don't dwell on it any more than I dwell on other shit I don't find attractive, nor do I feel any need to justify it. Does not being attracted to short men mean women are "insecure"?. It's all projection. Women get insecure at the thought of men finding them less attractive for this reason, hence why they obsessively try to convince men that it doesn't matter.
