Venting...I don't know how to talk to my friends about it

I have a friend and we had gotten really close within the past 4 months. He is such an amazimg friend and I trusted him so much. We never talked about being with each other or seeing one another as more than just a friend. But last week we were in his room just hanging and watching a movie and he kissed me. It felt so amazing. It felt as if he was sucking every once of oxygen from my lungs and filling me back up new. The next day we didnt talk about it. A couple days later we were intensely kissing and he asked me if I wanted to have sex. I was a virgin and I felt something that I couldnt describe and I didn't know how to say no. So I let him. I didn't enjoyed it. It hurt really bad and I felt hallow inside. He never asked me how was I. He just acts like nothing ever happened. Our friends dont know we had sex so everytime we all go out he talks about how he fucks a girl everyday. It hurts me to think that I actually thought I could be the one girl to change him. All I can think about is all he wanted was sex. I have always imagined I would loose my virginity to a guy I loved in a room full of candles and roses and It would feel my heart with happiness. But I let a guy who I have known for 4 months take the only special thing anout me. In his room on his crappy bed on a tuesday night. I am trying to be okay but it is all I ever think about when I see him.
