TITLE: I (17M) considering asking out a girl I like (17F) but I need some advice.
POST: I am somewhat a nervous and socially awkward person, which results in me saying some silly things around her even though I am trying to make my self sound cool and confident. 

I have liked her for a while now, we are both intelligent and in the same classes at school. I wouldn't say we are friends and we have different interests and tastes in music, but I find her really attractive and like being around her, any advice? 

Also I would say this is the first time I have felt this way about someone and my friends all think I like her even though I have not told them.
TL;DR: 
I have liked a girl for a long time, I am  somewhat socially awkward and am considering asking her out, I need help, please note I am new to Reddit.
