Query: If you're into vagina coloring books, then this is for you

I bought this book and my only complaint is that the vaginas weren't realistic enough. Sike--only kidding. I did buy this for a friend as a gag gift, and she laughed her butt off. Here is an interesting fact about it: it was drawn by a guy. But I guess that makes sense since guys probably see a wider variety of vaginas than straight women do. Anyway, this book is rad and I liked it.
