I was at my work Christmas party and this guy that I find so attractive asked me if I wanted to have sex with him. Drunkenly I said maybe. After the party was finished, we were so drunk and we caught the same cab because we don’t live very far from each other. He got out at my house and I said that I wouldn’t let him inside. He got in my car and I got in too. We started to kiss and then I said I didn’t want to have sex. He said I was a tease and then walked home. I feel terrible because I have to see him at work. Annnd...he has a girlfriend! What is wrong with me?!
