Welcome to 3fc! I'm so glad you found this site.
I don't think it's possible to pick where your body will lose weight and where it won't. However, you can do some weight training to build up the booty muscles and possibly give a rounder appearance? You may want to check out the exercise portion of this forum. I wish I could lose weight anywhere but my boobs, but I still haven't figured that one out yet!
