I once know a guy that’s popular with the ladies

And he has no redeeming evolutionary qualities
The guy eats like a horse, a lot of meat
He sleeps twice as long
He’s not too bright (failing exams, skipping exams and complain about failing class)
He’s very weak and skinny (despite eating that much meat)
And no he’s not good looking (average at best)

He’s a Chinese guy and other Chinese women couldn’t keep their hands off of him. He’s qualities are what these Chinese women look for

There is generally some particular explanation that makes a lot of sense. For example, I knew a guy that got lots of sex in a small town in NZ. What happened was that he had sex with this weird looking tall girl when they were kids. She told some of her friends about him and a couple of them also had sex with him. Then he became the go-to guy for sex and since he lived in the same town it carried over all the way to his adult life.
