Whenever we see each other in the halls at school he just slaps my ass. Why?
Most Helpful Guy
Guys like girl's butts. This guy likes to feel/touch/slap your butt, so he does so. He probably thinks you like it too because it's a sign that he thinks you're hot.
Since he's your boyfriend, it's a good sign. He's not creeping on you or anything; he finds you sexy. Take it as a compliment!3
