From my personal experience: my hottest friends have a very low bodycount. They’ve gone very long without a boyfriend or hookups and wait until they find someone they really like. This isn’t per se the hottest guy out their. Most of the time it’s a cool decent looking guy with who they share a lot of interests.
My more average looking friends have way more lays, some are straight up sluts. They fucked the hottest chads on multiple occasions. I always had the feeling they felt insecure being less attractive than their hotter friends and searched validation by fucking hotter guys than their friends.
I don’t think girls with high lay counts are super happy with their dating life. There’s for sure a part of that group that’s just very sexually by nature, but I’m pretty sure 90% does this for feeling like they’re good enough
