I remember my teacher being disgusted at kids talking about sex in the later years of primary school — she thought it was the end of the world, I swear, she literally sounded like she was “coming down with a case of the vapors!” But the truth is, naturally, that when adulthood is treated as prestigious, that every signifier of it becomes prestigious in turn, and claiming those prestigious things then serves as a way for kids to “rebel” against the norms forced upon them — except really, this “rebellion” in practice just means “growing up faster”, namely having kids’ childhood or youth stolen from them, such that the value of their labor can be stolen more efficiently in turn. That’s how I understand it, at least.
