I've been in college for a while, but I've still graduated high school rather recently. I can tell you all about it.
Not many guys got laid in my high school. Literally no one in my group of many friends had a girlfriend. The ones who have sex are high-tier Chadlites or Chads and practically any woman you can think of. I made a thread a really long time ago when I was still in high school (around when this site was first up) about nerdy girls who were in one of my classes ogling over a 6'8 football Chad. Their standards are bullshit in high school, and they're equally bullshit in college, except women twofold their lay counts after those four years.
The girls, despite being underage, had Tinder, and I'm pretty sure that's how they became cum repositories for older Chads, and which is why nearly every guy I met was single, except the Chads. I've mentioned this quadrillions of times, but I had a friend who would show me him swiping on Tinder because I had a class with him, and nearly every other girl I saw was a girl I recognized from my school.
