I'm going to turn it around and say you should consider what qualities you have and what kind of guys they attract. A lot has been written lately about women gravitating towards "bad boy" types. They're fun but aren't usually relationship material. So instead, think about like attracting like. Be polite to attract well-mannered guys. Be honest to attract honest guys. Be spontaneous to attract guys with a sense of adventure.
Given that looking is done with the eyes, it would help just to make sure a guy is there. If you see a guy, and you like him, and you start talking to him, and there are others with you that ask: "Who are you talking to?" That could be a indication of potentially serious problem on your part. Having determined that there is a guy that is maintaining some semblance of a physical presence preferably in front of you, then check to make sure he is breathing and has a pulse. If not CPR could be needed. Looking at your picture I know I wouldn't mind having CPR performed on me by you. (Assuming that is indeed your actual picture.) I may have to draw the line on the heart compressions though (Assuming I'm conscious while you are performing the CPR. Have a good day.
Find someone who you feel has things in common with you, has a good personality, make sure he hasn't been known as a cheater, try and avoid "players." It doesn't matter how cute they are as long as they make you happy! :) good luck :D
