Unfortunately, what you're experiencing is part of the so-called "celebrity culture" that exists.
We all have different expectations and that's why men date curvier women, or women want guys with brown eyes. How many women found the tall, dark and handsome man they wished for in their teens?
Concentrate on your personality, success, style. Develop a sense of humour; we like a guy who can make us laugh however tall he is!
Don't get hung up on your height, it will consume you and make dating difficult. If a girl comments quickly about your height, then she's not the one.
