15f and i hate being a virgin

know I'm a bit "premature," but all my friends are doing something sexual... while I'm stuck here, sexless. I have a girlfriend, yes, but she's not ready for sex (and obviously I'm not going to force her).

I came close to doing something a couple of years ago, fingering a woman. But that's all.

I also can't ejaculate when I masturbate, as it doesn't give me pleasure. I have too much sexual energy and I hate that I can't satisfy it.

Redditors, I need help or advice. Can you help me?

(and no, im not looking for a sex buddy. I'm a lesbian).
