Well, personally I like guys that are shy, smart, and completely humble. if a guy is too full of himself its very annoying. you should be careful though because not all girls are like me OR the same for that matter. overall just be yourself and if the girl you like doesn't like you then I guess it just wasn't meant to be. hope that was helpful.
I like guys that are confident and not fake. So long as a guy is just confident with who they are then they're attractive to most girls. But one thing I don't like is when guys do stupid things bcos they think it's cool like smoking drugs an underage drinking. For me they're major turn offs
I like their smile and when they're nice to people. Guys that are rude or pick on people to look cool I absolutely can't stand. I also look at a guys eyes a lot so I like pretty eyes :P and it'd be nice if they had good hygiene...they don't have to carry around germ x all day but...showers, washing their hands, and wearing deodorant are some things they shouldn't skip...and I don't like guys that drink or do drugs personally :D
