Hit puberty?
The size is correct and you already are in puberty. You will keep growing for a little bit longer yet. My friend Sheila who's currently 15, said her penis is approximatively 7 inches, and when hard 15. If your penis is as you say 3-4 inches at 15 you should seek medical attention immediately. Also, her penis is average size.
