As requested, to go along with the "Penis Research" thread... here is the female counterpart..

Average clitoral size (visible) of a woman: 1/4 to 1 inch

The Clitoris is the only human organ whose sole function is sexual sensation (OH.. us lucky gals)

Percentage of women who require some kind of clitoral stimulation in order to reach a sexual climax: 75%

During sleep, the clitoris appears to gain and lose an erection every 90 minutes, just like a penis.

Average increase in size of the clitoris during sexual arousal: 2X

Average length of time it takes the clitoris to return to normal size following orgasm: 15 seconds

Average speed of vaginal contractions during orgasm: 0.8 seconds

Average number of vaginal contractions during orgasm: 9 (range 3-15)

If pleasing erotic stimulation of the clitoris lasts from 1 to 10 minutes, 40 percent of women will likely have an orgasm. If such stimulation lasts for 20 minutes, 90 percent are likely to enjoy the pleasure of climax (lesson here: Foreplay is GOOD)


Masters & Johnsons published a chart of one woman who experienced a 43 second orgasm consisting of at least 25 successive contractions.

The only other creature on earth to have a hymen is..... a female horse.

Biological function of the hymen? NOTHING

In ancient Greece, aristocratic young girls were often ceremonially deflowered by having their hymens pierced with a stone penis of the god Priapus.
