Have you followed the story of transgender icon Jazz Jennings? He has a TV show on Discovery, I am Jazz, he makes appearances promoting the acceptance and promotion of transgenderism. You can find episodes and clips on You Tube. Upon reaching 18 Jazz went for genital surgery. Specialists in male to female surgery could not perform the operation. He had started taking puberty blockers very young. As a result his penis was infantile. This is what happens when boys are prevented from maturing. There wasn't enough penis to form a vaginal canal. After being turned down by doctor after doctor, one agreed to form a vagina using a portion of his lower bowel. That's what happens. A bowel resection. Life long difficulty with defecation.
Stop. Just stop. This is NOT reversible. It is NOT harmless. Anyone who wants to give children puberty blockers belongs in prison.
