Yes, he’s gaslighting you by saying: you’re okay with it when it’s consensual for you? but not okay with it when it’s not? there’s a huge difference between consensual sex and using violence and dominance to control and intimidate. This is absolutely a sign he will get more physical, the hardest/most dangerous step is leaving. If you do decide to, make sure you have a plan in place in case you need to.

Yes. Take it as the warning it is. If he does not stop, leave. You’ve pointed it out, he’s belittled it. He’s aware.
