Ahhh, I see. I thought you meant you were possibly judging based on an attraction to looks. My bad.
One thing I have noticed in past relationships (and I've had other people echo this sentiment) is that if you start seeing someone who you initially didn't find to be really attractive, as you spend more time with them, get to know them more, etc. somehow, as if by magic, they start to actually look more attractive to you than they were to begin with.
