Here's a harsh dose of reality:
People are superficial.
Let's get this one out of the way.
Men, women, children, potted plants. We're all fucking superficial. We care about how our partners look, because unless we're asexual, physical attraction matters.
So if you're constantly hitting on people that are objectively very attractive, or incredibly intelligent, or what have you, maybe you should lower your standards for your own good. Here's the thing: people usually date within their own range of attractiveness. Superbly attractive people stick together, while more average looking people tend to pair up. This occurs with people in terms of matching up with a partner on a similar intelligence level, interest, lifestyle, etc.
Interestingly enough, no one argues that you should try to make it work if you have nothing in common with the person you're trying to date or if there is a severe disparity in your respective intelligence levels. You simply accept the incompatibility and move on.
This really shouldn't be any different with appearances. As harsh as it is, the majority of those extremely attractive people you are salivating over won't give you a second of their time. People that attractive whether subconsciously or consciously want to date people of their own caliber; thus, people they themselves are physically attracted to. And there's nothing wrong with that.
I think it's time that we take a hard, objective analysis of what we have to offer in the general dating pool instead of demonizing those who present themselves at the upper percentage of the population in terms of looks. The main issue I take note in is that our appearances are an extremely sensitive topic and difficult to measure in any objective term.
However, I do want to conclude this with a straight-forward summary: people are shallow and want to date people they are attracted to - oftentimes this equates to people in their own "league" so to speak. Because of this, if you're someone who isn't particularly attractive by conventional standards, it makes no sense to expect that people who are attractive will flock to you.
