I'm of reasonable height (5'10), generally prefer girls around the 5'6 mark, but have had shorter girls, and girls that are taller. As long as they are also not tall and big it usually works fine. Yes, you have to make some adjustments to positions, but that's always present.
Tbh have generally found that its girls that are tall that tend to be somewhat self conscious anyway, and sometimes just being at ease with yourself in turn puts them at ease and can sometimes have great payoffs.
