"Anne is going through puberty, and she describes her changed vagina in honest detail, saying, "until I was 11 or 12, I didn't realise there was a second set of labia on the inside, since you couldn't see them. What's even funnier is that I thought urine came out of the clitoris." (Oh Anne, we've all been there.) She continues: "In the upper part, between the outer labia, there's a fold of skin that, on second thought, looks like a kind of blister. That's the clitoris." It's beautiful, visceral writing, and it's describing something that most young women experience. And yet I can understand that the junior Ms Horalek would have squirmed and wished herself elsewhere when this was read in class. We live in a society in which young women are taught to be ashamed of the changes that their bodies undergo at puberty – to be secretive about them, and even to pretend that they don't exist. Breasts, the minute they bud, are strapped into harnesses, and the nipples disguised from view. Period paraphernalia must be discreet, with advertisers routinely boasting that their tampons look enough like sweets to circumvent the social horror of discovery. For my generation, removal of post-pubescent hair on the legs and underarms was mandatory. For Ms Horalek's generation, it is mandatory for pubic hair too. Anne writes: "When you're standing up, all you see from the front is hair. Between your legs there are two soft, cushiony things, also covered with hair, which press together when you're standing, so you can't see what's inside." How must reading this feel for pubescent girls who've already internalised the message that they must spend the rest of their lives maintaining the illusion that their body hair doesn't exist."
