Years ago, I picked a book off a remainder table: Mirror Image: The Odyssey of a Male-to-Female Transsexual, by Nancy Hunt. Hunt describes her emotions following the surgical removal of her penis. She is elated, overjoyed. Good riddance to bad rubbish. She then describes the reactions of a patient whose penis has to be removed because of cancer. He is overwhelmed with grief.
