Most Helpful Girl
Depends. When you first get a crush on someone it's lust based. (Looks.) And that's usually for both genders. Though people can develop crushes for other reasons. (Maybe the person walks/talks a certain way, perhaps they've said something to someone that made you interested, etc.)
You have a few eye tag sessions and then you transcend into a different phase. Where you start to get to know each other (personality.) So I'd say that personality would be your biggest factor. I've known people that I wasn't attracted to on first glance, but eventually became more attracted to them the more I got to know the person. So I'd say yes. Sometimes attributes trump the looks. But every girl is different. I have lady friends that absolutely will not have anything to do with a guy if he isn't at least mildly attractive. I'm different, because I know that a serious relationship is based on so many different things, and sometimes good lucks just isn't enough to hide an ugly persona.
