Flat Chest

I’ve been getting teased a lot about how I have little to no assets when it comes to my boobs or my butt. I am 15 and I’m constantly teased by people by saying that they feel bad for my boyfriend because I have no chest or butt. Even my boyfriend said something to someone about me being flat chested. Is any natural way to make my boobs and butt bigger? I’m tired of getting teased and I really don’t wanna deal with it anymore.
