I feel sorry for the true shorties, although like Himuro said, there are always exceptions. Some girls are really picky about height though, and I think it's understandable. It sucks because there's nothing you can really do to be taller, but hey, that's life.
At 5'9 it's pretty rare that I don't have an inch or two on most women, but I still think ideal height for a guy is like 6'1. My dad's 6'1, fucker. I got the short end of the stick, har har.
