Was I raped?

I went to a party a while ago and everyone was having a few drinks.. me being me had a bit to much. There was this guy there that I had only met a few hours before and he seemed really cute and nice. Next minute we were talking and then we kissed, at this stage it was all a blur. I can only just remember this happening. After we stoped kissing we must have walked up the street and we started having sex, keeping in mind he wasn't that drunk yet I was absolutely plastered... I don't really remember much during having sex. The next day all my friends were talking about it and that we had sex and I was missing for a long time, but I don't remember this. Would you classify that as rape since I don't remember it or am I just being paranoid.
