Because they look nice and are nice
It depends on the guy and the butt. Some guys don't care so much about girls' butts. If you have a well shaped bubble butt you will not fail to have guys appreciate it.

So, you think guys like it, its true.They do this to stimulate the girl, means, they always find a way to start action, I think you got it. Another reason, that you want to get close to the person you like.
