Its like how women make fun of men who can't easily get sex, they assume because its so easy for them, that its easy for everyone, and if you dont get sex just as easily as they do, then there's something WRONG with your personality/attitude/not showering enough/etc (they dont normally say looks, because most of these girls who fuck 100s of guys are still dog shit ugly and would be incel themselves if they were male)
Just look at any articles written by normies (especially women) it all presumes you're having tons of sex and that its just something unavoidable like getting catching a cold therefore everyone must be just walk into sex like they do.
