Being very careful here...
If a person feels that their arms doesn't belong to them, or their eyes, or their ears, that they don't feel like part of their body - and wish to have them amputated, or removed, they'd be considered to have a significant mental health issue and psychiatric treatment be sought.
Even at the end of this treatment, if the person insisted that their arms/eyes/ears were not wanted - would an NHS doctor remove them?
If not, then why are we removing vaginas, labia, breasts, penises and scrotum - purely because someone has expressed that they don't feel they belong on their body?
