The vast majority of gen Z women are creeped out at the thought of dating a man more than three years older than they are (thanks feminism) even if they're attractive. A lot of Chads in their late 20s and early 30s pretty much have to lie about their age to get in bed with women who are early 20s.

It's all a farce to cover up the real reason that accounts for the vast majority of the discrepancy: they're sharing Chad. That's all that's it. Point blank period.
