Do looks matter?

I've always observed around me that whenever there's talk about relationships or crushes, the first thing considered is looks. Lots of people around me also tell that ONLY looks don't matter but looks do matter a little. But for me, it's hard to even care about looks. I mean as long as one is relatively fit and healthy, proper hygene. Now, I have not met a single person in real life that feels the way I do. Everyone always accuses me of lying too at times. I've always thought of people who care about looks as shallow but when literally everyone says it, I think I'm just the weird one going the wrong way about it. What are the reasons that such a person shouldn't be considered shallow? Am I missing something?

Edit - nvm I might just be a demisexual
