For me, I prefer a man to have long, nicely cleaned hair. Aside from that, though, there's not much. If he's intelligent, though, he has a much higher chance of getting my attention.
I would say the way they look and definitely the way they smell. After I'm hanging out with a guy and I can still smell his cologne on me, I can't stop thinking about him.
That is an imposable question to answer. It varies from girl to girl. They are not all from the same mold and think alike on everything. For example, it's just like how I might like the shy type while you go so the party girl. It's the same for girls as it is for guys.
