question ?

Everyone knows that New Year's eve was this weekend , and me being the person that I am , I got drunk . I was with my boyfriend and three of his friends but I was the only one drinking . I ended up staying with him because I told my dad that we would all be drinking , because that was what I was told . Anyways , we go to lay down and he had mentioned sex once before but it was never mentioned after that . When we were laying down , he started saying things about it and long story short , we had sex . But he knew I was drunk and I knew he was sober . How should I feel about this ? I'm not sure I would have done it if I was sober considering we've only been dating a short time .
