Walls of the vagina

The walls of the vagina have three layers. The inner layer is a mucous lining, similar to the mucous membrane of the mouth. It is rather fleshy, soft and slightly bumpy. It can be dry, especially when a woman is nervous, and very wet during sexual arousal or in some other cases. The middle layer is a muscular system. The outer layer of the walls of the vagina is fibrous. It connects the inner part of the vagina with other structures of the body. In the walls of the vagina there are numerous blood vessels. At the same time, there are very few nerve endings. Only the outer part and the very tip of the vagina are more sensitive. This explains why a woman experiences unpleasant sensations if a tampon or a contraceptive is put too deep into the vagina. Therefore, you should use both of them correctly. The inner part of the vagina becomes sensitive, if you press it. If you do this at the appropriate time, then a woman can have fun. The wall of the vagina

produces a substance( secret) that maintains the acidic environment inside the vagina and prevents the reproduction of microbes, including most bacteria. The substance changes its odor and taste depending on the phases of the menstrual cycle. In some other cases, it can stimulate a partner's sexual activity.

Along the anterior wall of the vagina at a depth of 3 - 5 cm, you can find the point Grafenberg. Ernst Grafen-berg in 1950 for the first time spoke about the fact that this point has an important erotic significance. Since then, there have been many disputes on this issue. Many women agree with the opinion of Grafenberg. This point can be stimulated by both the woman herself and her partner with the fingers or a penis in certain sexual positions during sexual intercourse. These include, for example, the situation when a woman sits on a partner or when a partner enters it from behind. Some researchers believe that prolonged stimulation of this point can cause an orgasm in a woman. Other

scientists say that the inner walls of the vagina are quite sensitive in themselves. Along the anterior wall of the vagina at a depth of 7.5 cm is the cervix, protruding into the vagina. The vagina and uterus are connected by the uterine canal, which passes inside the cervix. The thickness of the channel is only a few millimeters in diameter. Through this channel, sperm enters the uterus from the vagina. Most of the time this channel is filled with thick mucus, which prevents penetration of infection or semen into the uterus.12 to 16 days before the start of the menstrual cycle, mucus begins to "bloom", which greatly increases the possibility of sperm entering the inside of the uterus.
