80% of men have 0 sexual attractiveness. This doesn't mean that 80% of men are ugly, it just means that women don't see 80% of the male population in a sexual way. Think of it like pre-teen children. Most children aren't ugly, but none of them are sexually attractive.
Women want 80% of men to not express their sexuality or talk about it because it creeps them out.
You can be "average" looking and lack sexual attractiveness.
Few men are truly ugly.
So many 3-5/10 men get rated on the internet as "ok looking, not ugly" etc., but this doesn't mean they're sexually attractive. You don't have to be legit deformed or repulsive to be sexually unattractive. Women see all sub6 men as 0/10 sexually speaking. You're sexually invisible to women if you're not at least 6/10 PSL or top 20%.
Men on the other hand are attracted to many kinds of women. Men are willing to fuck anything with tits of any size and at least a slightly feminine overall appearance. Often a vagina is not needed (trannies.) Men see only 10-20% of fertile aged women in a non-sexual way, probably even less.
All of this of course doesn't mean average men don't have sex, even though many don't. If you're average or below average, you have to pay for sex one way or the other. These days even this is becoming less of an option for average and below average men because women often earn enough money to support themselves so they don't need to put up with a beta bux. Some women still choose to be with a beta bux for obvious reasons (free money, attention, favors, princess treatment etc.)
Most normie men enter relationships through social circles and friends. These relationships are almost always typical beta bux relationships that often end badly for the man. Women in these relationships are never satisfied because the only thing they get from these types of relationships is the princess treatment, bux, gifts, attention etc.
This is not enough to keep most modern women satisfied. They start to cheat with more attractive men, they treat their boyfriend/husband poorly, refuse sex (headaches, "I'm just not a sexual person sweety"), cuckoldry and most eventually file for divorce.
