Hey, I'm 16 too and I've been working out for over a year now. Its good to stay in shape, but the gyne doesn't go away
Mines worse than yours but we are about the same, body wise.
Since you've had it, it may not go away by itself either.
I say keep working out and if it still makes you feel uncomfortable, than talk to your parents about surgery. Or just deal with it. Yours isn't that bad
