Boyfriend grabbing your butt in public?

Does anyone else's boyfriend grab your butt in public? My boyfriend does this all the time, we were at the mall and he repeatedly does it, and once he slapped my ass when we were hanging out with his friend and his friend just stared at us in disbelief for a second and then started laughing. It's so flirty and surprising and I love it.. Anyone else? Also we are both graduated from high school so it's not like we are 13 year olds doing this 😅
