I want a nice firm sexy butt, mine's getting a little flat because I've been losing weight. Any ideas how I can be a little more rounded/tight? My butt has always been my best feature and now I fear that I'm losing it! I'd try squats and stuff but I like how thin my thighs are getting, I don't want them to bulk up and add too much muscle mass to them... I just want to be thin with a "tight butt" haha
