External Genitals in Female II
By peace | January 8, 2006
Below the external urethral orifice is the hymen, which surrounds the vaginal orifice. The hymen is a thin incomplete fold of membrane, which has one or more apertures in it. It varies considerably in shape and in elasticity, but is generally stretched or torn during the first attempt at sexual intercourse. The tearing is usually followed by a minute amount of bleeding.

The stretching and tearing of the hymen at a first copulation may be painful, particularly if the partners are apprehensive or ignorant of sexual matters. If the couple are well adjusted, the discomfort is minimal. Childbirth causes a much greater tearing of the hymen, and after divery only a few tags remain. They are called carunculae myrtiformes.

Just outside the hymen, still within the vestibule but deep beneath the skin, are two collections of erectile tissues which fill with blood during sexual arousal. Deep in the backward part of the vestibule are two pea-sized glands which also secrete fluid during sexual aurosal and moisten the entrance to the vagina, so that the penis may more readily enter it without discomfort. These glands occasionally become infected. They are known as Bartholin’s glands.
The area of the vulva between the posterior fourchette and the anus, and the muscles which lie under the skin, form a pyramid-shaped wedge of tissue separating the vagina and the rectum. It is called the perineum and of considerable importance in childbirth.
