Hymen position about a few centimeters

The hymen, a mysterious structure because it is in the intimate area of a woman. Many people are curious about it, and in the eyes of many men it has become a symbol of chastity! In fact, a “broken” hymen is normal!
The so-called hymen is a circular mucosal fold at the female vaginal opening, in the form of a film, located at the vaginal opening behind the urethra, behind the vestibule, its scientific name “vaginal flap”. The thickness of the hymen is about 1-2mm, it is rich in microvessels, nerve endings and connective tissue, and has a hole in the middle, about 1-1.5 cm in diameter, which is medically called the “hymenopore” and facilitates the menstruation of women by the hymenopore.
That’s why a “broken” hymen is normal! Because it is perforated, assuming that it is fully closed (of course, some people are born without a hymenal hole, presenting an atretic state that requires surgery), then where does the blood flow from during menstruation?
The distance and thickness of the hymen to the vaginal opening moves slowly with age. The hymen will be relatively thick during the baby girl period, plus the vagina of the baby girl is narrow, so the early hymen has a certain role in protecting the cervix and uterus. As the hymen grows older, the hymen becomes thinner and moves outward, eventually coming to the vaginal opening, which is usually within 0-3 cm of the vaginal opening in mature women.
For adult women, the hymen has no known biological function and its shape varies from person to person, with a texture similar to the tongue ligament, the tissue between the tongue and the floor of the mouth when the mouth is opened and the tongue is held up.
Depending on the shape of the hymenopore, it can be classified as round, oval, ring, sieve, crescent, perforated, etc. There are more than 30 shapes. The hymen varies in shape, from large to small, with one hole, two holes, or even no hole.
Generally speaking, a woman’s hymen will break and bleed the first time she has sex, but there are still about 30% of women who will not bleed or even bleed very little the first time, and the hymen may remain intact. This has to do with the shape of the hymen, like an umbrella-shaped hymen, which is more flexible and allows the “dingus” to pass through without breaking. In addition, the hymen does not only break during the first time, it may also break due to strenuous exercise (such as high jump, horseback riding, martial arts, etc.), improper cleaning of the private parts, improper use of tampons and other reasons.
Therefore, male friends please do not use “red” to identify the chastity of women! A hymen is not necessarily a virgin, no hymen is not necessarily a virgin, the two are neither sufficient nor necessary conditions for each other, if only to use the hymen to determine whether a girl is chaste that is too outrageous!
