Being a shorter guy myself, I can tell you the issue for me personally lies with the following, I'm almost always going to assume the taller girl is the one that won't want anything to do with me, so I usually won't bother unless they go out of their way to make it apparent my shortness doesn't bother them. I'm all for going after what you want, but not when the odds are almost impossibly stacked against you. That being said, I find taller women have a more, I don't really know, confident? I guess, presence, more in control of themselves. That to me is a big turn on. So if you make it apparent your height, and more to the point, their lack of, doesn't bother you, you shouldn't have an issue my dear.
guys would normally prefer smaller shorter girls because they feel dominate over them. but I am a 6foot 16year old girl who deals with the same problem you are having. I currently am dating a 6foot guy. and I'm always worrying baout what people are thinking on the days I wear shoes that make me taller than him. But he is told me that height doesn't matter to him or bother him. so you just gotta find that guy that doesn't care about it. and guys that do aren't worth your time. tall girls are hot. we got the long legs and guys dig it ;) so be confident and find a guy that will be a total sweetheart and height won't even begin to matter :)
