2.2.1 THE EXTERNAL SEX ORGANS
The female external sex organs consist of the mons Veneris, the major and minor lips, the clitoris, and the vaginal opening. All of these parts together are also often referred to collectively as the vulva (Latin: covering).
The Mons Veneris
The mons Veneris {Latin: mountain of Venus) consists of fatty tissue under the skin just over the pubic bone. On the outside, the area is covered with pubic hair, which first develops during puberty, and which makes the mons veneris by far the most conspicuous part of the vulva.
The Major Lips
The major lips (labia majora) are two thick and fatty folds of skin which extend from the mons Veneris downward, forming the outer borders of the vulva. On the outside, they are also covered with hair just as the mons Veneris. As the major lips usually lie close together, they seem to keep the other parts of the vulva covered.
The Minor Lips
Just beneath the major lips lie the minor lips (labia minora). These are two thin folds of skin richly endowed with blood vessels and nerve endings. As a result, they are quite sensitive to the touch. The minor lips merge at the top forming a single fold of skin covering the clitoris. This fold is also called the foreskin or prepuce of the clitoris, or simply the clitoral hood.

The Clitoris
The tip or glans of the
clitoris (gr. kleitoris: little elevation) is
located below the Mons Veneris at the point where
the minor lips meet, forming a foreskin or prepuce.
Externally visible under this foreskin is the glans
of the clitoris. The body or shaft of the clitoris
is a short cylindrical organ composed mainly of
erectile tissue, i.e., of two spongy bodies (lat.
corpora cavernosa) which can quickly fill with blood
and thus cause the entire organ to stiffen and
increase in size. Following it further inside, the
clitoral shaft divides into two legs, each of which
lies next to a bulb on either side of the vagina,
and all of these structures swell under sexual
stimulation. This is also true of spongy tissue
surrounding the urethra.

The glans
The glans of the clitoris is partly covered by the
clitoral hood or foreskin. It is possible for
secretions (smegma) to accumulate under this
foreskin, thus causing irritation and other
problems. The glans is extremely sensitive to the
touch as it is studded with innumerable nerve
endings. Unlike the penis, however, the excited head
of clitoris does not protrude but retracts under its
hood. The clitoris is easily excitable by mechanical
stimulation, and it plays an essential role in a
woman's sexual excitement.
A pleasure
organ
The average length of a clitoral shaft in
its unexcited state is less than an inch and most of
it is hidden from view. However, in the state of
excitement it may swell to twice its usual diameter,
and the rest of the tissue swells accordingly. This
entire system of erectile tissue might correctly be
called clitoral system or clitoris for short. This
would also make the parallels to the penis much more
obvious, even with regard to size. Furthermore, the
clitoris is obviously the principal female pleasure
organ, and it has no reproductive function.
An internal
organ
All in all, the clitoris is more an
internal than an external sex organ. It is listed
here among the external organs only according to a
now obsolete textbook tradition.
The Vaginal Opening
The vaginal opening lies below that of the urethra which, in females, is independent from the sex organs and is used exclusively for the release of urine. The urethral opening is very small, and it lies roughly halfway between the clitoris and the vaginal opening. By contrast, the vaginal opening is rather large, although it may be partially closed by a thin membrane called the hymen.
The hymen has no known physiological function. Nevertheless, in the past many people ascribed great significance to it. For example, it was believed that an unbroken hymen provided proof of a woman's virginity. However, such a belief is nothing more than a superstition. A hymen usually has one or several holes in it which may be stretchable and thus allow for the insertion of fingers, or even a penis, without tearing. On the other hand, in some women the hymen tears easily, not only as a result of coitus but also because of strenuous physical exercise or sports activities, in some cases, the hymen is even absent altogether. It follows from these observations that the condition of a woman's hymen does not prove anything one way or the other about her sexual innocence or experience. In most cases, the first coitus may very well be the occasion for the breaking of the hymen, but it can, of course, also occur during masturbation and petting, or when the woman first uses menstrual tampons. The tearing of the hymen may cause some initial discomfort and slight bleeding. However, there is no reason for women to fear any great pain.
On both sides of the vaginal opening, between the edge of the hymen and the minor lips, are the greater vestibular glands (Bartholin's glands), which correspond to the bulbourethral (Cowper's) glands in the male. The greater vestibular glands secrete a small amount of lubricating fluid. However, most of the vaginal lubrication needed for coitus is not provided by these glands but by the wall of the vagina itself.
