"A girl is like dinner, great if it tastes good, even better if it looks nice"- Mike Bowden
^You've gotten this answer a couple times already, just worded differently.
Every guy, whether he admits to it or not, feels this way about girls.
Me? I'd never date a girl that I wouldn't marry. And I view marriage as a life long commitment. For better or for worse. I've dated once (I'm 20), we talked about kids, beliefs, traditions, family differences, and ultimately decided it wasn't wise for us to get married.
What do I want? I want a girl who wants to be with me. One who isn't afraid to point out when I'm wrong, but not in an overbearing manner. I want her to be my best friend.
Ok, I feel silly now.
