Girls Need Some Meat On Their Bones
It just doesn't look good to be *that* skinny. There comes a point where you just get too... "pointy". I've had skinny girls on my lap, and even though they don't weigh much, they hurt more than chunkier girls just because their ***** dig in. Plus, there's a reason girls plump up around puberty and for pregnancy... we're *supposed to*. And still, bones sticking out is not sexy. That and if I were a guy, I'd be seriously afraid of breaking somebody that skinny. I can't imagine it's too healthy to be that skinny either... there's got to be some sort of deficiency in there somewhere... vitamins, minerals... immune system... I don't know.
There's a certain healthy weight between "too skinny" and "fat" that needs to be obtained. Even a little fat is ok, as long as you wear it right and you're fairly fit and healthy otherwise.
