Imagine it was normal for girls to carry diagrams showing their bodies and the parts they want well prepared. A separate diagram of their more complex mechanism... cough.. their brains of course. Anyways would it be useful to anyone? Do you actually do this. I could see it being part of a kink where like a teacher with the whip stick pointing each part with a hard smack to the diagram above her bed describing in detail what she likes and does not like. I like the intense vibe there myself at least.
