Many men say it doesn't matter whether a woman is virgin or not, but survey results show that in fact, many men have a virgin complex. Many people think that hymen represents chastity, so it is very important. But the role of hymen is not only that, hymen also has other roles. Let's understand the knowledge of virgin contact.
What does the female hymen look like?
What is the female hymen like? Firstly, it is important to know that the vaginal opening is located behind the external opening of the urethra, behind the vestibule. There are thin mucous membrane wrinkles around, called hymen. The hymen is a hollow membrane covering the outer mouth of the female vagina, about 1-2 mm thick. The front and back sides of the membrane are wet mucous membranes. Between the two layers of mucous membranes are connective tissue, microvessels and nerve endings. The hole in the middle is called the hymen hole.
The size of the hymen hole and the thickness of the membrane vary from person to person. The diameter of the hymen hole is about 1~1.5 cm, which is usually circular, elliptical or zigzag, and has a half moon shape. The membrane hole is inclined to a side of the septum hole, there are two small holes in the upper and lower or side by side, and there are also scattered holes like the small holes on the sieve.
The hymen can prevent the external unclean things from entering the vagina and has the function of protecting the vagina. Before puberty, because the ovaries secrete very little estrogen, the vaginal mucosa is thin, with few wrinkles and low acidity, so the resistance is poor. The hymen has the protective effect of preventing bacteria from invading the vagina; After puberty, with the development of ovaries, estrogen in the body increases, vaginal resistance is strengthened, and hymen gradually loses its role.
Hymen after sexual intercourse and childbirth
During the first sexual intercourse of virgins, when the male penis is inserted into the female vagina, it often breaks the hymen to form a crack. The cracks of hymen are often multiple, extending radially from the center to the periphery. Since the direction of male penis entry is generally downward and inward, the crack is deeper at the lower part of both sides of the vaginal orifice, reaching the base, which is called completeness rupture. During sexual intercourse, males exert excessive force and there are also lacerations in the nearby vaginal wall. For women who were born, the fetus was born in the vagina, which further damaged the hymen. It was incomplete everywhere, sometimes leaving only some residual protrusions, called hymen marks. If the baby is born by caesarean section from the incision in the lower abdomen, the hymen will remain in the shape after marriage if it does not pass through the vagina.
