I feel like it’s my fault

I was with my guy friend who I occasionally make out and fool around with and I wouldn’t give him head and he was trying to be dominant and he grabbed the back on my neck and tried to force my head down to give him head. And it triggered something and I got scared and then he got pissed off and left. I feel like a slut and I’m crying because I’m pissed. At myself. And at him because he wouldn’t pause and talk to me about why I freaked and he was like “I’m obviously not going to get what I want and you have other guys you’ll do it too but not me.” He’s saying he no longer wants anything sexual from me. Ever again. That he doesn’t want to excuses because every time we have the chance to have sex something comes up. This time I’m on doctors orders not to have sex because of a possibility of me having a hormone issue and tests they want to do sex interferes with it or something. He knows that. We should’ve just stopped but I kissed him. It feels like this is my fault.
