There is a slight change in the parameter towards an increase immediately after childbirth, but after some time the length of the vagina returns to its original values. Often men note a change in their sensations during intercourse with their wife after the birth of a child, but this is due to the fact that the folds inside the vagina are smoothed out.
During sex, the genital tube stretches by about 5 cm; in an excited state, this organ reaches 13-19 cm. However, according to Western research, the average length of the vagina during sex is 15-16 cm. This is exactly the same size as the male genital organ. .
After the decline of reproductive function, the parameter changes little; with age, the vagina extends by 1-2 cm, no more.
However, unless absolutely necessary, it is still not worthwhile to carry out independent measurements, as it can cause an infection. It makes no sense to find out the sizes out of curiosity. In a man and a woman, the genital organs usually have the length necessary for their close contact.
