Nearly all of the detransitioners I spoke with are plagued with regret. If they were on testosterone for even a few months, they possess a startlingly masculine voice that will not lift. If they were on T for longer, they suffer the embarrassment of having unusual intimate geography—an enlarged clitoris that resembles a small penis. They hate their five-o’clock shadows and body hair. They live with slashes across their chests and masculine nipples (transverse oblong and smaller) or flaps of skin that don’t quite resemble nipples.
