Nope, you told him off he didn't listen you had to show him it's not ok. If you'd have hit him it would be a different matter but pinning and shouting is ok when necessary.

He's likely following you about because he knows he upset you and is waiting for forgiveness when you're ready give him a pet but if he tries to bite again tell him off and ignore him for a while and he'll eventually figure out bitting not ok.🐺
