Intelligence, and I don't mean book smarts. I've been around quite a few people who are highly educated, but had practically zero common sense. Being intelligent to me is having a good blend of common sense, emotional intelligence, academic intelligence, and street smarts.
Self awareness also attracts me. Someone who can take a step back and evaluate themselves, see how to perhaps handle the situation differently then how they were handling it. It's something I'm trying to get better at every day... I'm still a work in progress though.
I do love a nice pair of legs, like damn... And a nice ass, well, damn yes as well! Curves are super attractive as well. Perhaps I shall stop before I get carried away.
