Boyish girls

Hey everybody! Can you explane me one thing. I think I'd rather a femme and I usually like girls like me, I mean, girlish gils. I really like everything femenine. I'm not really in this butch-and-femme stereotype, but it's obvious, that many feminine women prefer rather boyish type girls. And I don't really understand this, because I don't usually find them sexually attractive. Don't get me wrong, I'm not saying it's a bad thing - I respect it when people express their sexuality as they feel. The question is: if you are into boyish girls, what exactly are you attracted to? If not - just tell me what you think about this.
