Was I raped?

So I started talking to this guy again that I know  basically from been 11 to 17 we lost touch and got back into contact when we were 20-21 ish. Anyway we started talking and hanging out and I ended up sleeping with him once. A couple of days later we went out to a club and the plan was he wasn't drinking because he was going for a tattoo the next day and he was staying at mine. Anyway I got way too drunk ( unladylike and unlike me) but I had to be carried from the club but 2 guys and only remember flashes of the night. I remember been carried out and been in a taxi home with my 'friend' I then remember been sat on the toilet in my bathroom and been sick onto my feet and falling on the floor. I remember him coming into the bathroom and helping me up and that's about all I remember. Except maybe a flash of us having sex. I don't remember anything but I know what I'm like when I have a drink and I probably asked for sex and I know it happened and must have been rough because I was so so sore the next day. 

I always saw it as I put myself in that position for getting that drunk but after reading some stories on here was I raped? I don't know if he was drinking or not I can't remember but the plan at the beginning of the night was that he wouldn't be. But he then told a mutual friend I don't remember because I banged my head on the sink in the bathroom and I wasn't that drunk witch to me smacked of a guilty conscience because I was a mess. Anyhow nothing I can do about it now apart from never be that drunk again but I wanted your opinions. 

Thanks 

*Update*

It was 2 years ago now so I find it easyer to talk about I always thought it strange but never let it overly bother me. I can't ask him to fill in the blank bits for me because after that night he only ever spoke to me again once and that was when I saw him in the same club with the mutual friend. 

Thanks again
