I know what you mean, guys always giving you the "look", honking at you as they pass by with their cars, always being approached and always hearing the most pathetic pick-up lines. It's fun but tireing at the same time. But maybe your looking in all the wrong places, where specific types of people usually hang out. Maybe your personality doesn't shine enough through your outward appearance. Maybe your only looking for a specific type of person so you don't notice other people. Maybe your just judgeing the other person too quickly, assuming that they're only talking to you for your looks. When I first moved here, a lot of the people I know said to me that they were afraid/ intimidated because of how I looked and how I composed myself. But I was open to them and we all just got to know each other and grow to appreciate our qualities and personalities. I've been told that I have a beautiful mind and a beautiful face, you just have to know how to bring them both out.
Oh, and if all else fails, take Harsh Tranquil's advice.
