Most Helpful Girl
I feel like (not to stereotype) the shy guys I know have amazing personalities. That said, I think shyness is cute and usually means that the person is a bit more humble than a popular kid. And if they're good looking, bonus. So yes, it will mean a difference, but a lot of times that difference is positive.

No, not really. It also depends on as to how the other person sees it or their perception.
