Like @swampdragon said, all women are different, but I'll give my two cents. Yo soy una Americana mujer, so I'll speak from that culture.
I've been dating a guy for a few months and he makes me very happy. Desirable qualities are nice. I like an intellectual man, a man with drive, and a man that shares some of my core values.
Compatibility is also nice. When you can talk to somebody for hours and you don't know where the time went that's a good thing.
I also like a man with a little "rouged edges." This starts to get into stereotypes, but just like most men like a woman with "soft edges," most women like a man with "rouged edges." Now this is relative, what I consider "rouged" may be "soft" to another women. And although I can protect myself [in a America we have liberal gun right laws], it's nice to know I have someone who has my back.
But perhaps the most important thing, I want a man who will go out of his way to make me happy because I will do the same to make him happy. So going to girlie movies, even though you may hate them, it's nice to have you there. Or calling when you're going to be home late, even though you hate "checking in" I'm glad you did. Or you may hate the way I talk on and on about things you could careless about, but the fact you still listen matters.
Those little scarifices you make, makes a woman feel loved and adored. Somebody once said, men want to be respected and admired and women want to be loved and adored. So be the strong man that's going to always have her back, but also show her your gentle side that says, I'm only doing this because I love you :]
I hope this gives you a little insight...
