I prefer girls, but they turn into women. It's a process. Girls don't turn into something else. And if they do it's either a tragedy (a girl dies) or a gender reassignment (a girl becomes a man).
I love a girl, but I will have to either love the woman she will become or throw her away.
I choose to love the woman she becomes, if she has the mental features which attracted me to the girl in the first place.
