What are the changes in the female vulva during sexual intercourse? What are the roles of the vulva in sexual life
The change of the labia during the snap. During sexual intercourse, a woman's body undergoes a series of changes with changes in hormones in the body. These changes all urge women to seek more stimulation during sexual intercourse, especially in the labia area, where they hope to be caressed. It should be noted that the labia is an important sensitive point in a woman's private area, and touching it is like opening the door to love. Therefore, let's take a look at the changes in the labia during the snap!
Labia majoris
The labia majora is a pair of longitudinally raised skin folds located near the inner sides of the two strands, which contain abundant adipose tissue. The labia majora on both sides of unmarried or barren women are connected at the perineum. The outer surface of the labia majora is the same as the surrounding skin, with pubic hair growing on it and rich in sweat and sebaceous glands. Due to the pigmentation of the skin, it is darker than the surrounding skin; The inner surface appears to be often moist with mucous membranes. Some women have plump and thick labia majoris, while others have small and thin labia majoris. Some labia majoris have a deep color, while others are only slightly darker than the surrounding skin.
Changes during popping
Under normal conditions without stimulation, the labia minora on both sides of a premenopausal woman naturally close at the midline, covering the adjacent structures such as the labia minora, urethral opening, and vaginal opening, which has a significant protective effect on them. Only when a woman's libido is aroused, the labia majoris will open, exposing the covered area to the surface. Obstetrical injuries can disrupt the ability of the labia majoris to adhere to the midline, significantly affecting its response to effective stimuli.
For premenstrual women, the labia majora thins and flattens during the sexual arousal period, and produces an upward and outward elevation or displacement (leaving the perineum and vaginal opening), which is completed in the late stage of arousal or early stage of plateau. This may be caused by rapid congestion of the labia minora or protrusions caused by initial congestion of the outer one-third of the vagina.
Another possibility is an involuntary neurophysiological effect to eliminate any external obstacles to the expected sexual insertion process. During orgasm, there are no obvious anatomical changes visible. During the regression period, the labia majoris returns to its normal thickness and midline position. If a woman has already experienced an orgasm, the regression process will be very rapid; Otherwise, the detached and swollen labia majoris will take a long time to return to the midline position. If the excitement period and plateau period are prolonged, it can cause severe venous congestion and swelling of the labia majora, and even edema. Even after all sexual stimulation is completely stopped, it will continue for several hours before gradually dissipating.
For postpartum women, especially those with varicose veins, the reaction mode of the labia majora has changed, with significant dilation replacing displacement during the excitation phase and occasional 2-3 fold increase in diameter during the extended plateau phase. If a woman suffering from varicose veins only experiences a plateau period, labial bleeding will continue to subside for 2-3 hours. If she reaches orgasm, the congestion will subside much faster.
It can be inferred that the more severe the varicose veins in the labia majoris, the more severe the vascular congestion during sexual tension will also be. The labia minora is located on the inner side of the labia minora and is also a skin fold. There is no growth of pubic hair on it, and its surface is smooth, delicate, and elastic. It is mostly light red, moist and mucosal, with sebaceous glands distributed above it. Subcutaneously, there are blood vessels, elastic fibers, and a small amount of smooth muscle, with rich nerve distribution, making the sensation very sharp.
Labia minora
There are significant individual differences in the shape and size of the labia minora. Some people have narrow labia minora, while others have long labia minora that hangs down to the outside of the labia majora. Some are very thick, some are very thin, and some are irregular umbrella shaped; Some are as large as nail caps and typically have a semi circular shape.
Some people appear light red; Some are brownish red; Some people even have two colors for their labia minora, with the outer side being brownish black and the inner side being pink. Generally speaking, its color deepens with age and number of deliveries. Some African tribal women take pride in the length of the labia minora and pull it from a young age. As a result, the labia minora becomes thick and long in adulthood, protruding high beyond the labia minora, but its size has no significant impact on sexual response.
Changes during the snap
Whether it is premenopausal or postmenopausal, after entering the sexual arousal period, the labia minora will become congested and swollen, and its diameter will significantly expand, which can increase to 2-3 times by the plateau period. As the diameter increases, it protrudes from the protective labia majoris barrier, which extends the effective length of the vaginal tube during sexual intercourse by at least 1 centimeter and helps to open the vaginal opening.
Once the diameter increases, the labia minora is prepared for its most unique female sexual physiological response (color change). During the platform period, almost all women's labia minora exhibit bright color reactions. Non menopausal women change from pink to bright red and spread around the vaginal opening, including the foreskin of the clitoris.
The color of postpartum women has changed from bright red to deep purple red. As a rule, the darker the color change of the labia minora, the more severe the degree of varicose veins in the pelvic and labia minora. Due to the unique color change during the plateau period, the labia minora in a state of sexual response is referred to as "sexual skin".
Before menopause, women who have reached a plateau level of sexual tension and experience a change in skin color will experience the process of orgasm. To support the above argument, it must be assumed that specific forms of effective sexual stimulation that cause changes in skin color continue to be maintained without significant changes (the sexual skin mentioned here refers specifically to changes in skin color during the estrus period of female monkeys and orangutans, and should not be confused with what is commonly referred to as changes in skin color during the estrus period) .
