Was I raped...? Confused?

[cobwebs and logic]

I was at a small party last night with my two friends and two guys they met over Facebook. The guys were really nice, and we sat around playing a drinking game (circle of death) and as part of the game the one guy had to come up with a rule which was that the girls had to give him a kiss on the cheek before they drank. Both my friend and I went along with it until the game was over. After that, we were all pretty drunk and proceeded to play some music and dance around with each other. That guy started to dance up on me, and eventually pinned me up against the wall and started making out with me. I was okay with that at this point, it was just kissing I thought. He then proceeded to make his way with me towards the bathroom. I went in with him and we continued to kiss. It was dark, pitch black and I couldn't see anything or where I was and I have quite intoxicated. He began undoing my belt and pulling down my pants and I told him several times " I can't, I can't" and he kept shushing me. He then continued to take control, say down on the toilet and sat me on top of him and pulled down his pants. I kept saying " I can't do this, I can't have sex with you, I can't" and he continued to shush me ad carry on until we were having sex. I couldn't really comprehend that I was having sex with him until we were doing it and I continued to say "I can't do this I can't do this" but he didn't stop. In no way did I physically stop him at all, I don't recall if I said "stop" or "no" because it's foggy, but I do remember saying " I can't do this" repeatedly during it. I'm so confused on this because afterward I pretended like everything wa okay. I even had sex with him later that night, but this time I was sober and gave in because I already knew that I had done it prep idly that night so I figured it wouldn't matter, but it's really bugging me.., I didn't want to do it the first time, and I don't know... I am just so confused...
