I happen to agree. Appearance always fades with time, so it isn't something I place a lot of emphasis on. If I only liked a girl for the way she looked, she'd probably get dumped pretty quickly.
There are, however, a few other things that I look for in girls:
She must be an atheist. This is probably going to sound ridiculously stupid, but just hear me out, for now. The reason why I say this is because I'm an atheist, and I can't be around religious people without feeling awkward. It's not that I don't respect or tolerate other beliefs. It's that, when people say things like "I'm praying for you," or "I hope to God," or "he's in a better place," it just makes me feel very uncomfortable. When I crack jokes about religions, I don't want it to offend anyone, either.
On a similar note, I must feel comfortable around the person. Essentially, this means she can't be the pushy type. I much prefer the shy girls, mostly because I, myself, am rather shy. When people are loud, I either get uncomfortable, or my energy is drained. I can't live with a loud person. She can't be all like "Regulus, why won't you talk to me right now?" and she can't be like "I wanna go somewhere... can we go here? or here? or here? Waaaah, I'm bored!" I can't spend my entire day talking to people, because I just can't. And if I go anywhere, I'd rather it be someplace rural and quiet.
Even though I actually prefer the quiet type, I'd have to have someone who can hold a deep discussion. There's lots of ways people bond and relationships form, but I've only met a few people who actually enjoy talking about math, science, or philosophy in the same way that I do. Outside of my family, it's pretty rare for people to do that. That's very unfortunate, because it's pretty awesome when I can sit down on the couch with a cup of coffee and talk about thermodynamics, just for the hell of it. A lot of people bond by cuddling or doing things together, but in my odd opinion, talking to a girl about what love is, is far more romantic than simply saying "I love you."
One last thing: the girl must not be overly attached, needy, or whatever else you want to call it. If the girl meets the above three criteria, then I'd probably want to spend almost all of my time with her. Still, she must understand that I need my space. If I'm in a relationship, I'm still going to want to spend some time alone, and I'm not going to cut off my contacts with the friends I have now. That won't mean that I'd love her any less. Being needy just isn't healthy. I'd want her to be happy, even if I'm not around.
Really, other than that, I don't care about anything else. Health is important, but looks are superficial. It's what's on the inside that counts... and that's probably why I've never been in a relationship before.
