I'm a little shocked that anybody could claim that viewing a naked body at any age could be considered harmful. There are many cases where children would benefit from seeing a range of naked bodies, and realise that there are many people out there that look just like them. they don't have to look like the photoshop models who do get exposed. Body shame is a real thing, and the only way around it is for people to realise that bodies come in a wide range of shapes and colours, and they have no reason to be ashamed of theirs.
