Girls only?

Ok, I need some girl advice. I'm about 5'11 and 132lbs. Kinda of scrawny I know, but I've been going to the gym to bulk up. I used to be pretty shy, but now starting to come out of my shell. Not to be a bigot, but I'm not that bad looking and girls have asked me to do things before. but, I'm still really awkward around them and have no idea what to talk about. Its kinda of sad I know but I'm in 11 grade and 16 and have never gone on a date/had a gf. Is this weird and do you have any advice to improve my dating life??
