I am sort of short. I am 5'9". I usually don't have too many issues with it. One thing I would say to a girl that says that is "Height doesn't matter when we are both horizontal." That usually gets you a laugh, and shows you are comfortable in your own skin.
Also, Get some muscle mass. If you are short and rail skinny that is not going to help you out. I am pretty stocky and that seems to help a lot. I know a lot of taller guys that I am stronger than and could beat on easily. If you look more manly a woman will be attracted.
Also, one reason that girls really care about it is when they wear high heels they don't want to be taller than their guy. So go for a girl that can wear heels and not be taller than you. Now I understand if you are 5'4"-5'7" that is more of a challenge. But if you are 5'8" or taller I doubt height is that much of an issue as you are still taller than most girls.
