What do guys think of short girls? Like 5'1 short. Attractive? Unattractive?

I've met guys that all seemed to like my "smallness" as I'm rather petite, but then I met this one guy who said I was the shortest girl he's been with and he's only been with tall girls before and so on. So now I want to hear more opinions. And can short girls still be sexy?
