Personality is obviously important because conversation is such a crucial part of a relationship. Obviously looks are important too though. Guys with epic personalities who aren't physically attractive in your eyes are mates. Guys with epic personalities who are also physically attractive are potential partners. Simples.
0% looks, 100% personality. I am really not picky when it comes to appearance whatsoever. Though, I'm not all that interested in being in a relationship, either. I guess you could call me somewhat asexual.
