Yeah, women who ride the XX need to be tall and reasonably strong. My chick has a 32" inseam and finds it hard to deal with, but she has no upper body strength. I have a friend who is a motorcycle cop and she isn't comfortable on the XX because of height. Her favorite bike, a K1200RS, is heavier but low with all the weight at the bottom.
Also, it is positively retarded for anyone to ride a XX as a first bike. It is 2x so for a woman unless she's the size of an average guy.
