boy trouble

I have been single for four years, I have dated ALOT of boys but never had anything official. I am also a very picky person especially when it comes to liking a boy, ofcourse there has to be a visual attraction... I love a funny, down to earth guy but looks are high on my list aswell but I'm very particular with the all attributes and get turned off very easily if he has or does something I'm not generally into... Is this a bad thing? Am I too picky? How do I get over this?
