My male personal trainer spanked my butt today?

I've been seeing him for a couple weeks now and he's been really flirty with me. Throwing out sexual innuendos and very touchy. So today I was doing leg lifts and he comes over and asks me what number I am on and I said something around 60 and he spanks my a** and says "yeah!" It kinda put me off guard... I didn't say anything because I was just confused as to why he spanked me. I mean he's married but all the while flirts with me, touches me and by I mean touch I do not mean adjusting me... and then spanks my a**? What is going on?
