I can't date/mate with hot guys. Am I and idiot?

An oppotunity of having a date (actually a meet and f...) with a really hot guy came to me and I forze. I refuse him many times. To me I couldn't be with his since he was too hot for me and was expecting things from me I couldn't give him. I'm body akward. I'm sort of fat, I wouldn't say I'm down right ugly at all. But I still feel bad because I'd have liked to meet him but I seemed to reject the idea more strongly. Am I and idiot?
