In your instance when you know you're competing against taller 'subjects' perhaps it could be an idea to develop another attribute that would make the other person overlook your height. EG. Humour, personality, knowledge or a skill that could impress.
Good luck
But I do not like people making fun of us being so different in height.
When I was living in Paris I had a Japanese girlfriend, really beautiful, but only 5'. I did not like to go out on the street with her, because French guys were always making fun of us, and although I would have loved to punch them out, I couldn't be breaking the law all the time and lose my visa.
So most of our relationship was spent in bed in my apartment
That really annoyed her, but I really enjoyed every minute!
