Feeling used and horrible :(

So I thought I would give my ‘friend’ the benefit of the doubt and have him come over and hang out for a bit because he was a little down. Big Mistake.
He came over, sat down and we talked about what was bothering him and watched some television. We started kissing, and that was fine. Then he started to get grabby, and I tried to push him away. Again to no avail. This went on for a while then he grabbed a handful of my hair at the roots hard and pushed me down on him. He kept pushing till he was completely down my throat and I could barely breathe. I started choking and kept trying to pull away and he kept holding me there. I could feel myself about to vomit, tears streaming down my face from the force of it. I was kicking and slapping at him which proved as futile efforts. A little bit of vomit did come up, he didnt seem to care, but let me up. Just when I thought I had a second to breathe, he grabbed my hair again, I kept turning my head away saying no. He relieved himself on my face and chest while still grasping my hair.
It seems in an attempt to compensate, he wiped my face and put a blanket on me, kissed me on my forehead said goodnight and headed for the door. I was fuming, and hurt and just wanted him out.
My scalp hurts quite a bit and my throat feels sore. This time seemed more violent to me, but I’m scared I can’t trust my judgment. His contradictory actions confused me even more. He messaged me when he got home and I messaged back saying that was not ok and he said “I’m sorry…” So I guess to him that makes it okay now.
I feel disgusting
