People who smile and can make me laugh.
You've gotta be at least slightly less shy / quiet than I am, or else talking can be difficult and evenings tend to be stay-in all the time and it gets boring. It helps if some of your life-plans and goals match mine too (which is kind of difficult right now, because I'm living in a city I plan to abandon).
Hair (body, face) is usually a good thing, but I don't really have any sin-qua-nons. Tall can be inconvinient, but if the rest of the person's worth tippy-toes, then they're worth it.
Usually having any one feature that stands out is a plus (eyes-that-pop, big arms, that really awesomely wide or sometimes mischievously elfin smile, etc). I do have a really weird thing about long hair: it doesn't work for me and I just can't seem to get past it.

I have a pretty wide range of men I can be attracted to, and they don't all fit into any one "type". There's tendancies (shorter, stockier, more muscular instead of tall and thin) but they're hardly strict "rules", either consciously (that I'd rule out dating someone) or subconsciously (that my brain just finds random people attractive sometimes).
