The Diary of Anne Frank is the second best selling non-fiction book of all time. The only book that has sold more copies is the bible, and that's just loaded with sex, so no other book can compete.

But Anne Frank is chock-full of burgeoning sexuality. The young author – only 13 at the outset of the text and 15 when her amazing life came to an end – discovers herself, her changing body and her emerging sexuality.

Here are a few quotes that show us that historical texts can be as alluring as a great chick flick. Sex education à la Anne Frank:

“I'd like to ask Peter whether he knows what girls look like down there. I don't think boys are as complicated as girls. You can easily see what boys look like in photographs or pictures of male nudes, but with women, its different. In women, the genitals, or whatever they're called, are hidden between their legs. Peter has probably never seen a girl up close. To tell you the truth, neither have I. Boys are a lot easier. How on earth would I go about describing a girl's parts?” 

“Until I was eleven or twelve, I didn't realize 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. I asked Mother one time what that little bump was, and she said she didn't know. She can really play dumb when she wants to!” 

“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's see what's inside. They separate when you sit down and they're very red and quite fleshy on the inside. 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. Then come the inner labia, which are also pressed together in a kind of crease. When they open up, you can see a fleshy little mound, no bigger that the top of my thumb. The upper part has a couple of small holes in it, which is where the urine comes out. The lower part looks as if it were just skin, and yet that's where the vagina is. You can barely find it, because the folds of skin hide the opening. The hole's so small I can hardly imagine how a man could get in there, much less how a baby could come out. It's hard enough trying to get your index finger inside. That's all there is, and yet it plays such an important role!”
