Being interested in looks does not make you shallow, it makes you human. Unless a person is optically impaired, looks are the first thing most people with notice and develop a crush over. We humans have a way of turning natural biological functions, into moral failures. This isn't productive.

As one poster wrote, with age we often develop wisdom. We learn more about ourselves, and often (but not always of course) we find new, more lasting and important things to focus on rather than looks. Classically beautiful people are fun to look at. They can be kind, warm and wonderful. But so can less attractive people of course.

For most people, it's possible and ideal to find someone you are both attracted to physically and emotionally. I've known couples where one person is highly attractive and the other is much less so. Someone passing them on the streets would not believe they are a couple. Once you get to know them, it's obvious why there relationship works. The attractive person has "quirks" which most people would run from (nothing abusive). Actually they both have quirks and their personality and innate needs are perfectly matched. My point is, even if you are attracted to people who seem out of your league, there is still reason to think you might find your perfect package.

People often brag about not being willing to compromise anything for a relationship. This is usually a mistake. Successful relationships require a compromise. However, I think we would do ourselves a disservice if we fail to recognize the importance of physical attraction. If we aren't physically attracted in any way to a person, it's unfair to both them and ourselves to stay in a relationship with them. It would be more honest to stay "friends". But keep in mind, it's very possible to develop an attraction to a person you didn't find appealing at first, just by spending time and "really" getting to know them. So try that out! Just be kind and don't lead anyone on.

If you are looking for a lasting relationship, it goes without saying the persons looks will change. You and your partner will age, may gain some weight, could get in an accident and become disfigured. (Unlikely, but possible) If you truly love someone, their changes in appearance will not bother or alter the love you feel for them.
