Clitoris = Sex Pleasure
Know as "the clit", the clitoris is the only organ in either the male or the female body whose sole purpose is pleasure, which from a biological perspective might indicate that the female genitals are more highly evolved than the male's. Sometimes regarded as the golden button for women's orgasmic response, shouln't be approached in haste, sometimes wants to be caressed with vigor; other times can hardly tolerate being breathed upon.
Some clitorises nearly pop out at you and shake your hand; others can hardly be seen. Some clitorises are extremely sensitive; others aren't. Some change sensitivity with the time of the month. Not to worry, the sensitivity has nothing to do with its size, which can range from 2 to 20 millimeters in diameter. The clitoris is 1-1/2 to 3 inches (the glans, the exposed part, is only one fifth of the whole organ; the rest is erectile tissue that extends under the skin, fat and bone inside the body. You will only see the first 1/5 to 1 inch or so.) The visible portion of the clitoris is only the tip of the iceberg, so to speak. The clitoral system is mostly internal, made up of highly responsive sexual tissue.
Size makes absolutely no difference in the intensity of orgasm. Like the penis, a woman's clitoris becomes engorged with blood during arousal; and as with the penis, the measurements don't affect your sexual pleasure.
The clitoris is a somewhat cylindrical mass of pink or brown erectile tissue. It lies protected beneath the clitoral hood (prepuce) just above the urinary opening. The clit is highly responsive to touch and stimulation. Commonly a woman's primary orgasmic focus, its sole function is sexual response. No wonder we love it so much.
According to lastest tests on more than 500 sex active persons, 75% of women require some kind of clitoral stimulation in order to climax. Before and/or during sexual intercourse, it's the key to female orgasm.
Why is it where it is?
During the first few weeks, it is impossible to determine the sex of the prenatal embryo. By week 8, if the baby is a boy, the testicles develop. If the baby is a girl, the clitoris, labia and the rest of the vulva emerge from the same basic tissue. Our most erogenous bits are located in approximately the same place that a man's are -- right out in front. And because the clit is so sensitive, it's logical for it to be located where the amount of pressure on it can be controlled. Besides, men seem to complain about finding where it is now. If it were on the inside, it would be hopeless.
