it's 100% all mental based on how good looking the guy is RELATIVE TO OTHER MEN
Relative to other men? I don't think so, pretty sure if all guys were ugly girls just wouldn't want sex in general. True, competition is a bitch and that's why virgins are better - no one to compare to, no one to be worse than, but to be honest - looks are objective, and an ugly person in a crowd of hot people is just as ugly as them in a crowd of people just as ugly or uglier, and in a crowd of averages.
You wouldn't like eating spoiled food even if there was nothing else to eat unless you were starving (and you can live without sex it's not a basic need amirite IT), so you don't eat that spoiled food. It doesn't seem any better just because there's no good food around. It disgusts you no matter if you have better options or not, and even if it's prepared nicely, spiced, smelling good,, but it still tastes like rot, you won't eat it.
Which is exactly the analogy to 'improve yourself' or 'be yourself' (love the contradiction there). You can add bells and whistles to shit and trash all you like and yet once you get under the covers, it ain't any better. If anything, you're mad because you were sold good food and you got rotten food. So faking your way to sex is actually even worse than showing your power level/inceldom/whatever the fuck.
Normal people really, truly, believe they can fool lowlifes telling them that changing superficial things and things you can control matter. They don't matter, because you can control them and everyone knows and often can tell. It's the things you can't change that matter most, those objectively determine your quality because you can't advertise those as better than they are. Personality is great when it complements good looks and some nice social circles and cash, but it isn't doing shit for a person who has none of those because it's something anyone can fake with (a lot of) effort.
The fact some normal people who are more openly blackpilled will even say to you 'Why are you faking? I can tell you're (find normal substitute for incel/lowlife/loser). Don't pretend you're better than you are. I can see right through you. Stay down where you belong'. Of course, they won't say it as directly because normal people, including most women and about half to 2/3 of men, are super nuanced and suave, sneaking around words and insults and judgments without ever saying you're shit to your face directly so you don't have an excuse to tell them off or punch them in anger. Disingenuous bastards.
