Grayson Perry is saying this:
"People say if you’re trying to access some kind of feminine, emotional experience, dressing up is a rather crude way of going about it," he told The Guardian. "And I always go, yeah, but you don’t decide to be a transvestite when you’re a sophisticated adult – you’re a child. Our sexuality is formed in the Petri dish of our childhood."
So he is saying that cross-dressing is a sexuality, not a gender identity.
I am confused!
