It gets a 10 out of 10 on the graphic nudity scale, as these women are really spread wide open!
From the publisher: Over 100 females take off their panties and spread their legs in the name of educational / scientific teaching materials. If you are a medical student studying female anatomy, this is commonly thought of as the most vivid and shocking book you could possibly add to your educational curriculum. This collection of intimate nude photographs is intended to demonstrate the open and exposed female genitals and vagina. In addition to general education on the vagina, each full page color photo takes you inside the labia, with parted lips, lips held open, lips pulled aside, etc. There are no closed vaginas in this book, and every picture is up close and very, very personal. This book goes beyond Douglas O'Brian's previous book "100% Vaginas: Close-Up Photography (GRAPHIC)" in terms of the level of intimacy that is displayed, and is more similar in terms of imagery to "101 Gynecology Views" by the same author.
