Date Rape

What is considered "date rape?" I have been reading my Xanga a lot lately, just because so many more people post on it and I love getting to read other peoples stories but I only post on my blogger (whatever this is) A girl on Xanga was posting asking if she had been date raped one time because she got really drunk and high with a guy and remembers telling him no to sex but woke up sore. It left me wondering if I'd been date raped? Labor Day weekend of my freshman year of college I went home and went to a neighbors party. The guy I had dated all of my senior year was there and to avoid having to talk to him I got wasted and remember throwing up outside of the house we were at, CLASSY!! My best friend let him take me home. Other bits and pieces were filled in by my best friend the next day, maybe I should not consider her even a friend anymore. My car was parked at the gas station and without drawing a map its rather confusing because the party was about a mile south of my house and the gas station was about a mile north of my house so I had to drive past my house to get my car. I remember waking up, or whatever you call it when you aren't blacked out anymore, to Matt having sex with me in his car behind the gas station, again I state Classy! I remember mumbling that I had thrown up and to stop I wanted to go home because I was obviously drunk. And than I woke up in my bed the next morning with my car in the garage so?? Is it considered just drunken sex or would it be classified as date rape? At this point we had been broken up for 4 months and I was sleeping with someone else in Springfield. He had been doing heavy drugs and cheating on me with another girl which is why we broke up and even though he still called me, I never wanted to talk to him again.
