I'm a small girl, but I'm not attracted to a guy who is tiny like me. Most of my friends aren't attracted to small/really slim guys either. We like big guys, guys with some meat on them. I don't like steroid bodybuilders, but I like a guy with a healthy proportion of muscle and fat, not ripped up, but not lardy.
Most of my male friends have admitted that they're trying to lose weight, and none of them are fat at all. If anything most of them need to gain weight. Why do guys think that girls want to be with ultra skinny guys? Most of us don't find guys who wear smaller jeans than us to be attractive. We want men with size who seem masculine and strong. A guy doesn't have to be really tall or anything, but he can't be so tiny he can wear my clothes.

The problem is that a lot of guys are clueless about what girls really want. They actually apply their standards for what's attractive in girls and believe that girls find the same features attractive in guys. That's why there are so many guys who suck up to girls trying to be nice. It's also why guys try so hard to get skinny, because they think that since they're attracted to skinny girls, girls must be attracted to skinny guys. It's a false equivalency, and it's why so many guys can't get dates.2
