Most Helpful Girl
i know you said not to say it's all about personality (which it isn't, we're all humans and we're all at least a little superficial) but psychological studies have shown that girls/women tend to choose people based more heavily on personality than appearance while it is the other way around for men.
also, being attractive is very subjective. just because you think you're unattractive doesn't mean everyone does.
now answering in the way you wanted us to, a nice body does help because it shows you take care of yourself. your body is much more in your control than your face is. but having a nice body doesn't hurt. :)
