Thing is I want to gain weight on my hips and buttocks, but I don't know how to do that. Anyone please help me?

I've heard birth control pills make women gain weight (it works wonders for real skinny people). This girl I used to know was as skinny as me, and after getting on the birth control pill her ass got so hot. *drools*

on some other matter, i'm drinking this protein shake that's making me gain a few pounds and I wonder, what happens when/if I stop drinking it? Is all my gained weight and muscle mass going to be lost? *ick*

please, shine sum' light on me path, mates!
