I totally agree with what has been said to you already. My goodness that would scare me terribly!

Your Dom's first obligation is to keep you safe at all times and to never break the trust that has been established. If he does that then there is no hope that you will ever be able to be fully submissive to him, because you are going to be on guard for what he will do next.

If he needs to punish you then it's his responsibility to sit you down and explain exactly why you are to be punished. He is to make the punishment fit the crime.

"Getting back at you" sounds like a Dom that isn't in control of himself so how can he control his submissive?

Take care of yourself first and foremost.
