Vagina: a highly elastic reproductive organ
The elasticity of the vagina is sufficient to accommodate the penis of any man, so there is no need to worry that the vagina being too narrow will limit the insertion of the penis, nor is it necessary for the insertion of the penis to cause harm, unless in a state of illness China Sexual Health Network
Misunderstanding of vaginal elasticity
Some women find it difficult to engage in sexual intercourse, and even cannot insert a finger. In fact, this situation is not a problem with the elasticity of the vagina, but rather a psychological abnormality. When the penis is inserted into the vagina, as long as the woman is highly excited and psychologically normal, there will be no problem of the penis being unable to be inserted. On the contrary, if the woman is not excited at all, or if she is extremely nervous, fearful, or worried, even a small penis can cause discomfort during insertion.
Therefore, do not rashly insert before the woman is highly excited, otherwise the vagina may not have good elasticity. When obstetric injury causes a decrease in vaginal elasticity, it not only greatly reduces the sensitivity of women's external and proprioceptive sensations during sexual intercourse, but also affects the stimulation of the male's external sensations. This requires exercise of the pubococcygeal muscle to restore the muscle's tension, elasticity, and regulatory ability.
The anterior wall of the vagina in adult women is shorter but more elastic
The length of the vagina is about 7-9 centimeters, and the posterior wall is longer, about 9-12 centimeters. Usually, the front and back walls of the vagina are tightly attached to each other. The upper segment bends downward and backward, approaching the sacral fossa, and its lower end bends forward, forming an S-shaped sagittal plane of the vagina. The upper end of the vagina is wider and more elastic, with the vaginal wall surrounding the entire cervix. The circular cavity between the cervix and the vaginal wall, called the vaginal vault, is divided into four parts: anterior, posterior, and left and right. The posterior fornix, as a semen storage pool, is particularly deep and wide, which is conducive to sperm swimming from the vagina to the cervix. The strong elasticity of the posterior fornix also provides necessary space for an erect penis, while preventing excessive displacement of the cervix and potential sexual difficulties.
In addition to the vaginal epithelium and muscles, the vaginal wall also has a fibrous tissue outer membrane, which has good stretchability.
The vaginal epithelium is pink in color, with a layered squamous epithelium on the surface. The epithelium of the vaginal wall has many folds and muscle layers distributed in an oblique square grid shape. During sexual intercourse and childbirth, these folds will be fully extended and have strong adaptability. Therefore, there is no need to worry about the vagina not adapting to the needs of a thick penis and childbirth fetus.
