Is it immature to slap your girlfriend’s ass in public?

My boyfriend slaps my butt sometimes and I dont mind if its a little tap discretely but today he slapped my ass in public and he’s also touched my boobs and play slapped me on the head (only a tap but you know what I mean). I’m sick of this immature behaviour. Sure I like a bit of playing but not in public. I find it immature and degrading. Am I right or wrong on this?
