Carmen- maybe I am just old fashioned, but I would find his behavior extremely disrespectful. To me, it doesn't seem like you are trying to control him by withholding sex, it seems like you are trying to set boundaries to see if there is anything in the relationship worth working for and saving.
If he is making you uncomfortable now with his actions, he is not going to act any better when he is getting what he wants.
You deserve better.
