Sexually Assaulted?

I tried talking to the guy I had sex with a couple days ago and he called me a liar. He was really rough and told him to slow down and he kept going.. I told him to wait and he still kept going harder. I'm assuming I blanked out afterwards, cause when I opened my eyes he flipped me over and said "let me cum please" and he kept going and I couldn't move. My back, legs and waist hurts alot and I feel like something cracked on my left side. He denied everything. I feel really stupid.
