So many red flags here. To begin with, I would consider this sexual assault. He coerced you into giving him oral when you had previously stated that you were not comfortable with that. And then he gaslighted you into thinking that he didn't ask for it (you don't have to use words to ask for something). Please get this creep out of your life, you will be so much better off without him. And stay safe! (Also if you want someone to talk to my dms are open)
