This happened too many times and it hurt women the most.

Although having sex too often may seem to have little effect on women, it can actually harm their reproductive health.

Because women have an acidic temperament, the penis is relatively alkaline, and coupled with the bacteria brought in from the outside, the pH value of the vagina will soar after each intercourse.

Why does sex, a sweet thing, add so many unspeakable secrets to women? This is mainly because those foreign objects are not clean and they also damage the acidic environment of the vagina.

Ancient Enemy Invasion

The healthy female vagina is in an acidic state (pH value is 3.8~4.4), which is maintained by the lactic acid produced by the dominant bacteria - Lactobacillus to inhibit the growth of other bacteria. From an anatomical point of view, the vagina is the same as the outside world, but it is wider at the top and narrower at the bottom, which means that the opening is narrower, and the vaginal wall is usually relatively close-fitting. Therefore, the vagina is relatively continuously isolated from the outside world, maintaining a relatively stable acidic environment.

Compared with the acidic nature of the vagina, the male penis is alkaline. Because the epidermis of the penis is skin rather than mucous membrane, the pH value of the skin is about 5.5, so compared with the vagina, the penis tends to be alkaline. In addition, the penis is wrapped tightly, and sweat plus the male's "unruly" nature often leads to the proliferation of bacteria in the penis. Moreover, these bacteria are not the lactobacillus that can produce lactic acid that the vagina likes, but pathogenic bacteria that cause vaginal inflammation.

In addition, there are bacteria on the female vulva, which are different from those inside the vagina. Therefore, every time you make love, the female vagina is like encountering an "ancient enemy" invasion: female vulva bacteria and bacteria carried by the penis will be brought into the vagina, and coupled with the weak alkalinity of the penis itself (relative to the vagina), the result is that the ecological balance inside the vagina is broken. Moreover, during sex, the vagina is opened and comes into contact with the outside world more. In this way, the alkali is neutralized, the foreign bacteria increase, and it is connected with the outside world... Therefore, it is not uncommon that the pH value of the vagina will soar from about 4 to 7.2 in a short time after sex and maintain for 6-8 hours.

The health of the vagina is maintained by an acidic environment, so the chance of infection and inflammation increases. If it is during the menstrual period, the acidity in the vagina has been broken by menstrual blood, and coupled with the alkalinity and bacteria brought by men, the chance of infection is several times higher.

This also explains why women who have not had sex are less likely to be infected with inflammation under the same hygienic conditions, and why the probability of those who have sex being infected with inflammation is so high.

To sum up, please maintain personal hygiene before having sex, regardless of gender. "Auntie" is visiting, please abstain from sex. As long as you have sexual life, you should have a gynecological examination every six months. Also, please don't continue having sex!

Does using a condom make a difference?

In terms of pH changes, there will be no difference. Although qualified condoms are cleaner than unwashed penises, condoms are made of rubber. If you want to live comfortably and stably, you must have a neutral environment. The lubricant on the surface of the condom is neutral, with a pH value of 7, which is still very different from the normal pH value of the vagina (3.8~4.4).

Throwing the baby out with the bathwater, missing out on benefits

Does this mean that we will all become ascetics? Of course not. In addition to the practical effect of conceiving a baby, the enjoyment of sex is also something that cannot be given up.

Although the acidic nature of the vagina is easily broken, the vagina is not so weak that it loses its ability to self-regulate and restore itself. Otherwise, the history of vaginal development would have truly become a history of blood and tears for women. After sex, the acidic environment is broken, but the vagina returns to its previous relatively stable state. The estrogen and lactobacillus inside the vagina will work hard to produce lactic acid and re-establish the acidic environment that the vagina likes. Of course, the condition is not to continue having sex. Otherwise, the self-regulation and recovery of the vagina is limited. Beyond this limit, everything will go against health.
