Dude you're 16 and like a sophomore in HS. Relax.
I was 300lbs at 5'10 in my SENIOR YEAR. I hadn't even gone on a date let alone kissed a girl.
I had the same mentality as you for a really long time. Become friends with a girl, develop an emotional relationship and then they'll see how cool I am/was. I'd then ask a girl out I had grown close to, and the answer was always 100% no. I became bitter and looking back was essentially /r/incels or /r/niceguys. Just thinking that all girls cared about was how guys looked, and you could be an asshole as long as you looked good and still pull girls.
This is me now. Yes it took work, yes it wasn't fun. But fuck do I think I look good. I spent way to much money on clothes and reframed my entire being from when I was 18 to when I was 19 on a physical level. Got a gf a month after I turned 19, and then had to reframe myself MENTALLY after a breakup earlier this year (20, turning 21).
My entire point is that you should really be working on yourself at this stage. Creating an emotional connection with girls and THEN asking them out doesn't work like 99.99999999999% of the time. What does work is improving yourself and then being foward with the way you think and the things you say.
