From my perspective, the only things I care about in a woman are:
1) Can you be around them for long periods of time?
I've had girlfriends where I couldn't stand to be with them for more than a couple of hours. Be it due to them talking about stuff I don't care about, I'm more interested into watching the game, or if they're just annoying after so long. The one I have now (we've been dating for over 2.5 years), we hang out, go running, play sports, play video games, everything. In short, there has to be a connectivity of personalities.
2) What do they look like?
What they look like tells you a lot about a girl. For example, if they wear lots of make up, they're obviously sensitive about the way they look, which is a big turn off for guys. Guys don't dig low self-esteem. Their body type is another. If they're toned and in shape, it tells you that she has self-respect and she cares about her body and herself.
3) How do they interact around people?
A big issue with girls is that they get jealous over the dumbest things. They'll hold grudges against other girls for the rest of their lives over gossip or a stolen boyfriend in high school. Males like it when a woman acts the same way and has the same personality, whether it be home alone together or out hanging with friends.
Aside from that, it's all personal taste. Hope that helps MG.
