Speaking directly to your question, no - I never wondered. To me it just seemed obvious. One fact has verry little connection to the other so why would chaniging one effect the other? Statisics show red cars are faster. Does that mean if I paint my car red it will be faster? I think statistics would show a moderate chance of being born gay and a lesser chance of being born trans. Now how likely is it to be born both? Probably way less than either. So to me there is no surprise - it just makes sense.
