The female erectile sex organ (or phallus)

In the absence of testosterone, the genital tubercle forms the female phallus, called the clitoris. The clitoris is made up of the glans and the body of the internal organ. Unfortunately, the clitoris does not respond with a lover. Neither do women respond to erotic stimuli (experience mental arousal) with a lover as men do. Even for a responsive woman, orgasm is an occasional pleasure she enjoys alone by focusing on surreal fantasies.

A woman’s sex organ (clitoris) is separate from her internal reproductive anatomy (ovaries, uterus and vagina). The sole function of the clitoris is to be a sex organ. Unlike a man, a woman has separate anatomy for urination (the urethra), reproduction (the vagina) and orgasm (the clitoris). These three functions are all combined for a man and provided by the penis. A woman’s anatomy is more evolved (because each part of her anatomy has only one function) but a man’s anatomy is more practical and convenient.

The sex organ (penis or clitoris) is the only erectile organ of the body. When a person is aroused (their mind responds positively to eroticism), the brain causes an increase in the rate of blood-flow around the body. Our physical arousal, which involves blood flowing into the corpus cavernosa causes swelling to varying degrees, called tumescence, of the sex organ.

The clitoris is largely an internal organ. Only the glans (or bud) is visible externally. The glans is hidden by the labia majora as well as pubic hair. The glans is covered by a clitoral hood formed in part by the fusion of the upper part of the two labia minora. The clitoris has corpora cavernosa that are smaller but analogous to those of the penis. During arousal, these tissues trap blood. After orgasm, the blood is released back into circulation.

The clitoris is the homologue of the penis but the female phallus develops very differently to a male phallus. The clitoris is smaller and the corpora cavernosa measure up to 5 inches in length. The body (shaft) of the clitoris consists of two parallel erectile chambers (corpora cavernosa), smooth muscle and connective tissue (collagen and elastin) surrounded by a fibrous sheath (tunica albuginea). Because the shaft and the glans of the clitoris have no subalbugineal layer between the erectile tissue and the tunica albuginea, the clitoral organ becomes tumescent (swollen) with effective sexual stimulation but does not become erect (rigid).

As a consequence of never being rigid, the clitoris lacks the erotic sensitivity of the penis. Stimulation by a lover of the clitoral bud (even over the clitoral hood) causes women to have a range of responses from indifference to pain and discomfort. When a woman casually stimulates over her clitoral glans, she obtains little pleasure because she is typically unaroused. The clitoris is not involved in reproduction. The clitoris is like a stub of a penis. The clitoris does not function as a phallus that is capable of penetrating and impregnating another person. Consequently women do not have a sex drive to engage in intercourse. Neither is female orgasm a requirement with a lover so women are not mentally aroused with a lover.

The stimulation used by a responsive woman (when masturbating alone), involves massaging the skin over the glans and pressing her fingers down into the internal organ (either side of the vaginal opening). This external manual massaging is combined with internal pressure on the clitoral organ, achieved by a rhythmic thrusting motion and clenching the buttock muscles. None of this stimulation is sensationally pleasurable in itself. Mental arousal (by focusing on conceptual fantasy) and physical arousal (tumescence) provide some mild pleasure. The key pleasure of female masturbation revolves around the sensations of sexual release at the end.

Female orgasm is a hangover from how the sexes evolved. Female orgasm is a miracle because we usually only evolve characteristics that have a purpose. We are also likely to lose characteristics that have no useful function. Male orgasm triggers ejaculation but female orgasm has no role in reproduction. The clitoris is the source of female orgasm, which provides a woman’s own personal pleasure. The clitoris only responds when a woman consciously focuses on becoming aroused by using fantasy.

Both the penis and the clitoris extend back into the pelvis in between muscles in the lower abdomen. Since it is largely internal, the clitoris does not have the same significance for a woman as the penis has for a man. Unless a woman is responsive, she is quite unaware of having a clitoris. Similar to an iceberg, what we see on the outside is only a small portion of the total organ. Both sexes clench the buttock muscles in the build up to orgasm to put pressure on the internal organ and so achieve orgasm.

During subconscious periods of arousal, increased blood flow (in older women) can cause the internal clitoral organ to swell. The swollen pubic area is very noticeable both to the eye and to touch (by pressing down either side of the labia). Clitoral tumescence does not indicate conscious arousal nor does it help with orgasm. The main benefit of clitoral tumescence is an increase in sensitivity in the internal pelvic organs during intercourse. In younger women there is little discernible swelling of the clitoris.

The clitoris, which is the phallus of the female, is the homologue of the penis of the male. (Alfred Kinsey 1953)
