There is always a sexual technique you don't know when learning the seven cold knowledge about sexual life

Sexual activity not only brings offspring, but also has a beneficial and healthy effect on people. A happy sexual life can generate positive emotions, eliminate nervousness, and release endorphins, which are natural pain relievers. Please do not introduce the benefits of sex one by one. Please understand the cold knowledge of sexual life.

What is the cold common sense of sexual life?

1. It's impossible to lose weight through sexual activity

Online rumors suggest that a one-time life can consume a lot of calories, equivalent to jogging 3000 meters. In fact, after research, it was found that sexual activity does not consume much energy, with a maximum of 550 calories consumed, making it impossible to lose weight through sexual activity. In addition, having sex too frequently can actually cause a series of problems such as decreased libido, impotence, and premature ejaculation.

2. Smoking after sexual intercourse can affect sexual ability

Many men like to smoke after sex, but in fact, it can harm the body and affect the penis. The cause of penile erection is congestion of the corpus cavernosum of the penis. If you want to congest, the corpus cavernosum must have enough blood. If blood flow decreases, it can affect the erection of the penis. After the end of sexual activity, the blood circulation rate throughout the body increases. After smoking, harmful substances in tobacco will be quickly absorbed by the body. Especially nicotine stimulates the brain center, causing rapid contraction of the smooth muscles of the corpus cavernosum, ultimately leading to a decrease in penile blood flow.

3. Women are not so concerned about the size of their penis

Almost all men are concerned about the size of the penis. Generally speaking, when the penis is erect, it is 12.4 centimeters, and when in a fatigue state, it is 7.1 centimeters. There is no need to be too insecure within the above range. In fact, what women are most concerned about is whether the penis can be firm and long-lasting.

4. The first sexual encounter may not necessarily result in bleeding

Whether the first sexual life is bleeding is related to the hymen. There are holes in the middle of the hymen. The number, size and shape of holes are different for each woman. The first time I woke up, the bleeding was caused by the tearing of the hymen. Generally, with the growth of age, the hymen will become thinner and more elastic. The first time I live, I will not necessarily bleed. Therefore, whether there is bleeding during sexual intercourse during the first sexual intercourse.

5. Masturbation does not cause impotence or premature ejaculation

Masturbation does not cause significant harm to the body, and moderate masturbation can regulate the body and mind, alleviate sexual repression and desire. The difficulty in erection and decreased libido caused by masturbation are only temporary, so don't worry too much. However, the frequency of masturbation must be mastered.

6. Excessive pubic hair is not related to sexual desire

Some people believe that the more pubic hair, the stronger the libido, but there is actually no scientific basis for this. The exuberance of pubic hair is related to genetics and male hormones, which do affect male libido, but are not the only determining factor.

7. Watching pornographic movies won't make you happy

Watching pornographic movies not only won't bring happiness, but also can bring sexual impulses to men. However, the only drawback is that there is a significant gap between men and real life. Watching pornographic movies can lead to a decrease in their confidence in sexual activity, with the most terrifying being frigidity.

Sexual life is a matter for two people, and only when both men and women cooperate can they achieve a beautiful sexual life. Occasionally experiencing impotence or premature ejaculation once or twice, do not lose heart or carry too much psychological pressure. When erectile dysfunction and premature ejaculation continue to occur, it is necessary to go to the hospital to identify the cause and not use aphrodisiacs on your own.
