He was often chastised by his father because, in the effort to satisfy this impulse, he put on his sister’s clothing. If he happened to see a ballet, only the male dancers interested him. Since he could remember, he had had a horror feminæ. If he happened to visit a brothel, it was only to see young men. He was, indeed, a rival of prostitutes. If he saw a young man, he just looked at his eyes ”
