Nobody in the storyline made the boys do it and it was a competition to be dressed as a holy sun maiden. A literal religious figure/symbol. There was nothing adult about what those kids did nor wore, same with the other contestants. The point was to show your knowledge on the subject and to have fun, not to be provocative. Your point would only make sense if they didn’t want to participate and they were forced to do 18+ acts to garner attention which does not apply here.

Why in the world do we have kids cross dressing author might need a police check.
