Sexiest Personality Traits

I know what you're thinking; this thread has been done before. Well, yes. Though in this thread I would like people to delve deeper into the specifics rather than broad generic traits. So, what little personality aspects are the sexiest? You don't have to put it into the context of an actual person, think about the traits themselves. Edit: Just to reiterate; this is the [i]sexy[/i] traits thread, not just the nice/desired traits.
