You’re having a hard time getting girls. That sucks. I remember what it was like when I was a young teenager and couldn’t get any. It sucked. But the sad fact is that most young teenage boys are repulsive—that is, they are half-formed works in progress. Girls mature physically more quickly than boys, which means most girls your age already look like young women and they’re generally attracted to (slightly) older boys—and there you are, still looking like a short, hairless chimp.
But don’t despair. Your awkward/repulsive stage will pass. In the meantime, here’s what you need to do: Worry less about getting your young teenage self laid and start thinking about getting your 18- or 20-year-old self laid. Join a gym and get yourself a body that girls will find irresistible, read—read books—so that you’ll have something to say to girls (the best way to make girls think you’re interesting is to actually be interesting), and get out of the house and do shit—political shit, sporty shit, arty shit—so that you’ll meet different kinds of girls in different kinds of settings and become comfortable talking with them.
Some more orders: Get a decent haircut and use deodorant and floss your teeth and take regular showers and wear clean clothes. Go online and read about birth control and STIs, and learn enough about female anatomy that you’ll be able to find a clitoris in the dark.
Masturbate in moderation—no more than 10 times a day—and vary your masturbatory routine. I can’t emphasize this last point enough. A vagina does not feel like a clenched fist, nor does a mouth, an anus, titty fucking, dry humping, or e-stim you will vary your routine now so that you’ll be able to respond to different kinds of sexual stimulation once you do start getting the girls.
Good luck, kiddo.
