女人阴道到底有多深呢,你的长度够吗?

During sex, many men worry that a woman's vagina is too deep and their JJ is not long enough. How deep is a woman's vagina, and how many centimeters does a man's genitals need to meet the needs of women when they have sex? Not only do men have sex with women There is an interest in private parts, and women are also very interested in their own private parts. Because it is not directly observable.

Some sources say 8-9 centimeters, and others say 12 centimeters. Experts believe that the length of most women's vaginas is 9-10 cm, but this 9-10 cm is the length of a woman's normal state without sexual intercourse. But if a woman has no length once intercourse, the real "bottomless pit". Because the muscle tissue of the vagina has a retractable function, when sexual intercourse, the woman's vagina will adjust the depth at any time with the man's JJ. So no matter how big, long, or thick a man's JJ is, women are not afraid.

 For example, the JJ of most yellow men in Asia is 10-15 cm and the thickness is 3-4 cm, while the JJ of white men in Europe and America is 12-18 cm and the thickness is 4-6 cm. The most terrifying thing is African black races, their JJ length is generally more than 20 cm, the longest reaches nearly 30 cm, the thickness is 5-7 cm, and some even reach more than 8 cm. A conclusion is drawn from this. The vagina can accommodate any size JJ insertion. It is not an exaggeration to describe the "bottomless pit".

According to the data verified in this regard, the average length of a female vagina is generally 5 to 7 cm, and women who have given birth will elongate slightly. The average length (depth) from the vaginal opening to the uterus is 6 to 10 cm and can be 2 to 3 cm wide.

With the increase of the number of births and the increase of age, the vagina also extends. For each delivery, the anterior vaginal wall grows by 0.5-1.2 cm, and the posterior wall grows by 1.0-2.0 cm.

Due to the injury of the birth canal during childbirth, vaginal and perineal tears often occur, involving the perineal body and the tissues attached to it (such as urogenital septum, bulbocavernosus muscle, levator ani muscle, etc.).

Sometimes there is no obvious laceration of the vaginal mucosa and skin, but the deep muscles, fascia and nerve fibers are broken, and the supporting tissues of the vagina and external vaginal opening are weakened and relaxed, and some need to be repaired for the front and rear walls of the vagina.

Therefore, women who have given birth only stimulate the clitoris, labia and urethra during sexual intercourse, which is difficult to satisfy sexually, and often requires simultaneous stimulation of the cervix and fornix in order to promote the arrival of orgasm.

     Structural features of a woman's vagina

The structure of the vagina is mainly narrow at the lower part, and the lower end opens into the vestibule of the vagina through the vaginal opening. In the virgin stage, there is a hymen attached around the vaginal opening, which can be annular, half-moon, umbrella or sieve. After the hymen is ruptured, a hymen scar is left around the vaginal opening.

The upper end of the vagina is wide and wraps around the cervix and vagina, forming an annular depression between the two, called the vaginal dome, which can be divided into anterior, posterior and two sides. The posterior part of the vaginal dome is the deepest, and is closely adjacent to the rectum-uterine depression, separated only by the vaginal wall and a layer of peritoneum. Clinically, it has great practical significance, such as the ability to drain the effusion in the depression through the posterior fornix.

It has a super expansion coefficient

It has a super expansion coefficient, and a survey conducted in 2006 showed that the vagina is 6.35 cm long and 2.54 cm wide at the opening. Of course, this data is measured at rest. When a woman's libido is high, the diameter of the vaginal wall will expand to 5.08~7.62 cm, and the elongation will be about 15.24 cm - this process is like inflating a balloon, even if your partner is gifted with super-sized biological weapons, It can also enter your body smoothly, all the way unimpeded.

In addition, when a woman is in labor, the cervix and vaginal ligaments become soft enough to allow the baby's head, about 10.16 cm, to pass through the vaginal cavity. During the four weeks after giving birth, the vagina gradually contracts. But for most women, getting back to their prenatal shape is difficult. However, prolonged sex will keep the vagina elastic.

Women's vagina also sweats

People often talk to their hearts, but few people pay attention to the feelings of private parts. In fact, women's private parts also have monologues, but you don't notice them. Let's talk about what secrets women have in their private parts.

The private part is an embarrassing problem that many people find difficult to talk about, but it is indeed a problem that many people cannot handle correctly, but it is indeed not a small problem. .

The vagina (don't make a fuss) - it's the must-have channel of life and the ultimate path to sexual pleasure. The vagina's voice is being revived in the sex vocabulary. A survey on women's private parts found that 77% of women will carefully observe their private parts through the mirror, and 53% of women are willing to discuss the use of this area with him. But here's the discouraging fact: 45% of women don't know any health secrets about this area.

it's not just a channel

In layman's terms, it's a dead end. You don't have to worry about some items such as hemostatic pads, Condom, sex products, etc. disappearing mysteriously in the vagina, and finally all the way to the uterus. Anatomically, the cervix is a reliable door between the uterus and the vagina, but the cervix is not completely closed. Open the gate to discharge the waste in the body. In addition, it can allow semen to flow into the uterus, preparing a port for successful human creation.

It also sweats profusely sometimes

In this magnificent flower, a large number of sweat glands are buried, which ensures that you can maintain a normal body temperature by evaporating sweat in time during your exercise. In addition, when a woman's sexual desire is aroused, the blood vessels in the vaginal wall dilate and secrete mucus (lubricant), also known as "sweating". The amount of mucus secretion is not closely related to the level of sexual desire. Some women only need a slight stimulation to secrete a lot of mucus, while other women's genitals are only slightly wet when their sexual desire is high. It mainly depends on whether you and your partner are familiar with foreplay techniques and whether the rhythm is clear.
