FOR A MOMent i thought u were talking about AGEs... I was gonna say 'U gotta be fking KIdding me'.
To answer your question, yes it could very much happen. You and others might think you are a 6 but to him maybe you are more. every person have different taste. I'l give u a quick example... i happen to LOVVVVE pretty girls with large dark eyes and dark hair, although other guys might see those traits as Normal or average, but to me she's a fking Princess.
But there is another possiblity, some good looking or reasonably good looking guys would go for less attractive girls because those guys might have low self esteem or because they think she will be easier for them to get and have sex with or whatever (depending on what the guy is thinking to do with her). So be careful.

I don't want to be rude, but I think this isn't possible. That's why I already convinced myself that I will end up with a guy who's a 5, because I'm also a 5. I can't wish for something I will never have.
