I went on a blind date to a prom when I was a sophomore with a guy that my cousin swore up and down was a real sweetheart but his girlfriend dumped one week before the prom. I went with him and he was a perfect gentleman. We had a really good time and then he asked me if I wanted to go to the after party with all his friends. I said yes b/c I knew my cousin was going too so I felt o.k. Once we got there, he underwent a complete personality change. He told me that since all the bedrooms and bathrooms were being used by some of the other couples at the house, we'd have to have sex in one of the closets.
I just stared at him in shock and told him that I was a virgin and did NOT do that kind of thing. He looked at me and then told me to "get your own ride and go the fuck home" if I didn't put out.
I found my cousin talking with a group of friends, told her what happened, and she very nicely went up to him and threw her beer in his face.
Her date and her then took me home & apologized for making me go out with the creep. They didn't know he was a real asshole. He must have hid it well.
