I hope the link works. It's to an insta post about a Dutch tv show that has adults getting fully naked in front of 11&12 year olds who can then ask them anything they want about their bodies.
This episode has only transgender adults.
The blonde at the start of the line talks about euphoria after a double mastectomy. The one in black boxers talks about not wanting to be naked because there's a vulva under the shorts so finds it more comfortable wearing boxers with a packer. The one with long dark hair mentions male to female sex reassignment (to be fair this person actually seems a bit awkward/not quite sure how much to say to the kids).
The kids shown say it was weird at first but quickly became normal.
I don't think anybody's body should be seen as wrong or freakish but there's 101 ways to convey that differently to prepubescent (as they appear to be) children. And I have no idea about laws around indecent exposure in The Netherlands - I can only imagine there aren't any.
