Me or my body?

I was talking with a few of my friends the other day and the conversation we had was pretty interesting. My friend said that she had come to the conclusion that most guys only go out with a girl based on how she looks. She was extremely annoyed and wanted to share her opinion with the rest of us. I had to agree with her. Guys tend to look at hair, weight, teeth, body style, and just the face in general to decide whether or not they would date a girl. It made me think, does that guy want to date me because he likes who I am as a person? Or, does he want to date me because I'm skinny and have straight teeth? It hurts to think that I would only be wanted because of the way I look. What if I got in a car accident and my face was destroyed? Would he still want me? Does he really want me or my body?
