The uterus is a place to breed new life. During the process of sex, there will also be a series of significant changes. The uterus of an adult woman is about 7-8 centimeters long, the bottom is about 4-5 centimeters wide, and the thickness is about 2-3 centimeters. 40-50 grams, the lower end is connected to the vagina and there is a complex reaction during sex that gives the female a wonderful feeling.
In sexual love, when the clitoris is stimulated, the uterus will move slowly upwards towards the back, so that an oval-shaped concave basin space is formed between the cervix and the anterior and posterior walls of the vagina, as if a tent is erected and semen can enter this part. If G is stimulated during sexual excitement, the uterus moves downwards and outwards. In contrast to the above-mentioned increased response, male fingers or genitals will feel a great deal of force pushing you outward.
When a male genitalia is long enough and rhythmically stimulated to the cervix, it can undoubtedly enhance women's sexual feelings and bring about deeper sexual reactions. However, if the male genitalia is too long, if the depth of insertion is not controlled, especially in women When not fully excited, it will cause discomfort and even pain to the woman. Especially when the man is rough and violent, it will bring more pain to the woman.
In the high tide period, the typical response of the uterus is the rhythmic contraction of the uterus muscle, which starts from the upper part and gradually descends, ending in the lower part of the uterus. This contraction is similar to the contraction of the myometrium that occurred in the early part of the delivery, but the amplitude of the contraction is partial. Small and high frequency. When the climax is released, the uterus of women who have not had childbirth will subside within 10 minutes. The time required to have children is 10-20 minutes. ▲
