Hmm I have a theory...take it loosely though. What if you enjoy seeing the comparison of a tall woman and short woman...because your instincts sense a battle for alpha female...in the wild kingdom after all, a big animal is typically dominant over a little animal. I realize we are not in the Darwin world now, and theres a lot of little girls that can kick tall girls butts...so I dont want to make generalizations. I wonder if it is an instinctive reaction. Maybe you are looking for an Alpha female.
