How to make boobs smaller?

Hey so i am 15 and i have 32DD cup size. I excersize at least twice a day playing some of my six sports. Most people say when they loose weight, boob is the first to go. I beg to differ. I am 5' 6 and 120 pounds and i sill aintain that size. I eat a fully organic diet. Are there any other ways to make my chest smaller naturally? I have considered reduction, but it is not much of a possibility considering my age. For me, breasts just get in the way. they get me unwanted attention from some unfriendly people and i would love for it to stop. yeah so any suggestions?
