I never said you were. It a personality thing, all about how you present yourself. You can be good looking, but if you act like a doof, girls aren't going to like you. It can also be that you aren't the girl(s) type.
Are you looking for a long term relationship or a quick fling? Maybe the girl is turned off by your choice.
The thing I figured out is try not to look too desperate, guys and gals make that mistake alot.
Also when with a girl try to be yourself, and I know you here this but heres what it means, act the way you would around the girl as you would with your friends. Don't think with your hed think with your head.
And most importantly, let them come to you, don't go to them. In other words let them take it as far as she wants to go, dont be all grabby. And if you have the chance to kiss her and your positive its the right moment, for gods sake do it! I make that mistake and not do it!
Most Girls enjoy a guy who'll poke fun at them (jokingly of course, dont go and call her The Fattest Thing Since Butter), Alot of them are turned off by the sappy-love-song type...at least until they get a little older. That being said, it's important that she understands that you're not just going to get up and leave her as soon as you get what you want. She wants someone dependant, someone who won't cheat on her.
Yep, Girls are Tricky, but not as bad as most guys think.
Yes, I suppose I did generalize a bit too much in my previous post, but I'm just speaking from experience. You're right though, Every Girl is Different, but it doesn't mean that they aren't similar in alot of ways either.
