It's tempting for most people to make some kind of joke here, but think about this:

There is a book called The Clitourist: a guide to one of the hottest spots on earth; it is a lighthearted but informative book on women's sexual anatomy. The Library of Congress catalogues this book as QP265, which is a subsection of Science - Physiology. Another, titled The Breast Book: An Intimate and Curious History, gets catalogued at GT498, which is a subset of anthropology having to do with the cultural aspects of the human body.

There is a book called The Clitourist: a guide to one of the hottest spots on earth; it is a lighthearted but informative book on women's sexual anatomy. The Library of Congress catalogues this book as QP265, which is a subsection of Science - Physiology. Another, titled The Breast Book: An Intimate and Curious History, gets catalogued at GT498, which is a subset of anthropology having to do with the cultural aspects of the human body. The Clitoral Truth: The Secret World At Your Fingertips is HQ447, which is a subset of social sciences dealing with sexuality, specifically women's masturbation (there is, in fact, no Library of Congress category for male masturbation).

However, The Penis Book, which is similar in tone to The Clitourist and The Breast Book, gets put in category PN6231, a classification it shares with Accountants' Comic Dictionary, The Treasury of Clean Teenage Jokes, Wackronyms and How To Embarrass Your Kids Without Even Trying. That category is "Humor".

So, at least according to the Library of Congress, which sets the standards for every library in the United States and many parts of the rest of the world, women's sexual anatomy is worthy of cultural, medical, scientific and social significance. Men's sexual anatomy, on the other hand, is a joke. Congratulations, ladies. There's at least one place in the world where men are the second-class gender.
