Why do guys always like skinny girls?

I HATE SKINNY GIRLS um hate them i think they r nasty looking i like girls that have a belly it turns me on. so not all guys like them most guys who don't like skinny girls still date only skinny girls cuz they don't wanna be judged but when they get older they start to realize that it doesn't matter and they start dating the girls they like no matter what people think. so not ALL guys like skinny girls
