TW: He play hit me a bit too hard?

TW also kind of inappropriate:
Me and a guy I’m talking to were watching a movie yesterday and he wanted to cuddle but we were struggling to find a cuddling position.
So I ended up laying my head on his lap and when I did that I noticed he was hard. So I pointed it out and he was like don’t do that. And I was like okay. So a minute or two later I was wondering what I did that made him hard so I asked and when he asked what I was referring to I tapped it (as a way of teasing him). Then he was like no stop again and hit me this time.

I can tell he did it unintentionally but it was a little too hard and I kind of wonder whether that’s a red flag or not. The next day he asked what was wrong because I was being off and I said he hit me a little too hard yesterday. He apologized and said it was a reflex and that he didn’t mean to. Then when I afterwards said it wasn’t a good look he was like “I’m sorry okay”. He mentioned he’s been trying to control his sexual urges.

What do you guys think?
