When my boyfriend and I make out, he's always touching my butt and rubbing it. I like it a lot, but does he do it only to please me or because he likes it too? I'm Brazilian and have a large butt (normal body size though- 5'6 130 lbs, flat stomach) but he's white and I didn't think white guys liked large, bubble butts (it's firm and upright, not sagging). We're both 18.
