In my experience tall women have less confidence. Seems counter intuitive but that's what I have witnessed as a short woman who is into women (of all sizes).

Short women are seen as cute and attractive. I think it's a myth that men do not have a height preference. Most prefer a woman who is shorter than them and they often give more attention to small women.

Many tall women have serious self-esteem issues and that could be a reason why they hit on you less. Sadly there isn't much research into it. Most research in preferences is focused on what women find attractive in men.
