I looove spanking, and getting spanked. Never to the point where it actually hurts though.
It's just fun. Its a little smack and a grab of the butt. It just feels good and kinky, can't really explain it. But its just fun, and is absolutely NOT because of depression and low self-worth at all!! Its playful.
Spanking to the point where it actually really hurts though, I don't get either.
