The external genitalia are collectively known as the vulva which consists of the labia majora, the labia minora, and the clitoris, together with the perineum behind and the pubic pad of fat covered by pubic hair in front. The labia majora, forming the major protection to the vaginal entrance, contain fat and are covered by normal skin containing both hair follicles and sweat glands. The labia minora are folds of delicate, sensitive skin which contain no fat, hair or sweat glands. The clitoris is situated in front where it is entirely protected and covered by the skin at the junction of the labia minora. It is a small cylindrical shaped organ approximately half an inch in length, at the end of which is situated the highly sensitive glans rendering it the most delicate and sensitive part of the vulva. Being composed almost entirely of erectile tissue, similar to the penis, it becomes engorged and swollen under the stimulus of sexual excitement. The glans is normally covered by a fold of protective skin which can be retracted to expose it. The clitoris is the female’s most erotic organ and it has no function except to enhance the woman’s sexual excitement and response.
