This was the book to read in upper elementary school. I remember it being whispered about a lot among the girls and passed around with a certain page open. It was a book about sex, and of course we all wanted to know!
You could get it from the school library if you had a signed permission slip from your parents, but then the boys, and perhaps even the teacher, would see that you had the book, so that really wasn’t a viable option. At some point I got a copy of my own, which I still have. Strangely, I don’t have any memory of how I got it, but I remember it made a huge impression on me. It was a safe way to put myself in a situation I hadn’t encountered yet and allowed me to consider what sexual intimacy would mean for me.
