Get to know The Clit

A distinguished researcher explains the role and function of the clitoris in this January 1964 issue of Sexology magazine. Scans included! From Modern Mechanix:

Like every other part of the normal body, the clitoris varies in size from person to person. Usually it is 1/4 to 1/2 an inch long, about 1/4 of an inch thick. Like the penis, it is made up of two parts, the head and the stem. The penis has skin wrapped all around it, which covers the tube of the urethra, or urinary canal. But the clitoris has, instead, a cape or hood of skin, the ends of which (called the labia minora, or small lips) stretch down inside the folds of the outer lips.

When a woman becomes sexually aroused, the clitoris becomes erect by filling up with blood. In some women, the head and the stem of the clitoris both swell up, whereas in others only the stem swells. After swelling up, the clitoris draws back under its hood, like a snail into its shell, and is hard to locate. It stays in hiding when the woman reaches her climax or orgasm of sexual excitement, and then slowly comes out again.
