The physiological hurdle of women's private parts introduces 15 little common sense of women's private parts.

The female reproductive tract has two natural lines of defense, one is the "anatomical line of defense", there are five hurdles from the outside to the inside, and the scope of women's virginity often involves the first and second hurdles.
The first hurdle
In the vulva, both sides of the labia magnum naturally close, covering the vaginal orifice, making it difficult for bacteria to enter.
The second hurdle
In the vagina, due to the role of the pelvic floor muscles, so that the front and back wall of the vagina close, vaginal orifice closed, can prevent external pollution. If the puerpera, postpartum vaginal relaxation, defense function has been weakened.
The other is the "physiological line of defense".
On the one hand,
Under the influence of estrogen lockthecock , vaginal epithelial cells continue to metabolize anal dildo , proliferate and thicken, increasing their resistance to pathogens.
On the other hand
Under the action of vaginal bacilli, the glycogen rich in vaginal epithelial cells can be decomposed into lactic acid to maintain the normal acidic environment of the vagina and inhibit the pathogens suitable for reproduction in the weak alkali environment, which is called vaginal self-purification in medicine. Therefore, although there are some bacteria in the vagina of healthy women, they usually do not cause inflammation.
15 Common sense of female "Golden Triangle"
Secret 1 was formed four months before birth.
The reproductive organs of the embryonic age will gradually mature and eventually allow the baby to have its own sex. When the embryo is about 10 weeks old, if DNA determines that it is a baby boy, then the "baby brother" and testicles will gradually take shape. If it is a baby girl vibrator for vaginal atrophy , then the reproductive organs will grow into vaginas.
Secret 2 not all vaginas have hymen
If you don't bleed during the first night, it may be because you inadvertently broke the hymen-a thin film usually attached to the opening of the vagina-can damage it by exercising and placing tampons-and some people are even born without a hymen. On the contrary, some people's hymen are so thick that they have to be removed surgically-making it possible to have sex or place tampons.
Secret 3 is only part of the reproductive organs.
It is wrong for many women to regard the vagina as the whole of the female reproductive organs. Although the clitoris, vulva and urethra are less than an inch from each other, they are still separate parts of the reproductive organs. So, how should a woman's vagina be defined? The vagina is a moist muscle tube that begins in the vulva and extends about three inches toward the pelvis to the cervix (the opening of the uterus). Vagina will bring us the best part of sex, which is not only the place where "good friends" flow through every month, but also the exit where our baby leaves its mother in the future.
Secret 4 there are a lot of bacteria in the vagina
Don't be afraid, it is these bacteria that maintain the acidic environment in the vagina and protect us from infection. In your vagina, there are about 15 kinds of bacteria that are camped out as guardians against harmful microbes and bacteria.
Secret 5 will have a smell.
A healthy vagina will give off a slightly different smell, depending on how you eat, how you smell, and the cycle you are in. Other sources of flavor include sweat, eating garlic, semen mixed with secretions, and so on.
Secret 6 yearns for fresh air
Like other parts of your body, your vagina needs fresh air. If skinny jeans or rayon underwear make her breathless, bacteria will multiply and can easily cause infection.
Secret 7 tickles.
Dry skin, sweating double dildo , and thick clothes can make you feel itchy or tingling. However, severe itching that lasts more than a day or itching from inside the vagina is not that simple. It may be a bacterial infection or other reproductive organ disease.
Secret 8 also needs a health check.
Every three months, you should have a self-examination for your vagina. The method is simple-open the labia, observe the appearance of the vulva with a mirror, and check for abnormal growth and normal color of the vulva. Usually there will be no big problem with our examination, but if you find any suspicious lumps or bags, be sure to see a doctor for a professional examination as soon as possible.
Secret 9 rejects fragrance
Scented soaps or scented detergents can damage pubic tissue. The fragrance ingredients in these cleaning products may cause skin discomfort. The correct washing method is to rinse the vulva with clean water instead of soap. Doctors advise women to use toilet paper without additives, scented sanitary napkins and fragrant personal cleaning products.
Secret 10, you didn't lose too much blood.
Although you may suspect that you have at least shed 500ml's blood, the reality is that menstrual bleeding is only a few tablespoons. So, we don't lose too much blood.
"Secret" 11 is busier and healthier.
Regular sex will make your vagina healthier. Because sex exercises vaginal muscles to keep them tight. In addition, the more mucus secreted by excitement before sex, the less likely it is to cause vaginal damage during sex.
"Secret" 12 secretes more or less mucus
When women are excited, the vagina secretes mucus, which is a natural lubricant for the human body. But how much is normal? Some people secrete a lot and the whole vagina is wet, while others are only slightly moist-which experts say is normal.
"Secret" 13 "she" makes a sound during sex
The vagina makes a sound during sex, which is mainly caused by the way your partner enters. If he gets in and out every time, he is bound to leak air in and out, and when the air is squeezed out of a relatively closed environment, it sounds like farting.
Secret 14 plastic surgery can help you create a perfect couple
The latest "knife" trend is not breast augmentation or breast reduction, but plastic surgery for your secret garden. The doctor will create a small, symmetrical, tight labia according to your needs, and float it into a tender pink if you like. In this procedure, known as labioplasty, plastic surgeons use scalpels or lasers to reshape two labia to make them look more symmetrical. However, because this is a simple "cosmetic" surgery, there is no need to do it, so few doctors recommend it. Another operation, "vaginoplasty", mainly involves plastic surgery on the loose vagina to restore the original compactness of the vaginal muscles relaxed due to age or multiple births. But doctors say this type of surgery is only applicable to mothers with severe vaginal muscle relaxation, which costs about $3500 to $7000.
Secret 15 your daily secretions will have two tablespoons
During ovulation, your hormone production will peak, during which time about two tablespoons of secretion will be produced every day. This peak period is determined by the uterus, and secretions bring out the aging cells and tissue in the uterus and form new ones-- this is the way the uterus cleans itself. For the rest of the non-ovulatory days, your daily secretion will be only about half a tablespoon.
