Don't worry, at 15 year old penis size depends almost entirely on when you started puberty. If your friends started puberty early their penises will be bigger than yours now, but you'll catch up quickly. If you started puberty late, then maybe your penis just started growing. Most guys' penises are finished growing by 17 or 18 years old. Don't worry, your penis will finish growing and look great.
