I'm (22f) secretly enjoying a short massage session after workout

So I’m in my second month of personal training sessions at a local gym. Recently, my trainer started giving me a short massage session after our workouts using a massage gun. I’m kind of ticklish, so it took me a bit to get used to it. Anyway.. sometimes he moves the massage gun up and down my inner thigh. When he gets to like halfway up, it feels 'funny'. We usually just chat during this. Like the workout, or everyday stuff like what we’ve been up to, food, movies, etc... its just a short session in a public area..

But there's been a few times when I had to shift or move away to stop him because it got little too funny., and we just continue chatting like normal. And this another time, when I’m lying on my stomach and he runs the massage gun over my rear thighs and glutes... I’ve had a few funny moments there... Quite pleasant... I wonder he realizes...
