The Cunt Coloring Book; artistic fun for the entire family! Even hardware store bull dykes waxing philosophical on the Amazon message board agree:

This book is so wonderful. Never mind the fact that I’ve been having a blast breaking out the crayons and coloring the beautifully drawn vaginas. But this book helps to de-mystify and remind women (or men) of the beauty of the female parts. This book contains about 25 drawings of flower-like genitalia. Each drawing is beautiful and unique – just in the same way that every woman is beautiful in a different way. This book presents women’s sexuality is such a matter-of-fact and positive manner. I wish all women could see this book as a child, again as a teen, and again as an adult – to remember to always be proud and never be ashamed.

Vagina coloring books are not the only thing that present women’s sexuality in a matter-of-fact or positive manner. Take this for example. And this.
