Sex is essential for both men and women, especially a harmonious sex life, which can help release stress and further heat up the relationship between husband and wife. But there are some rumors about sex life circulating in life. These rumors are deeply rooted in people's hearts and can even lead to family breakdown.

Which 5 “shy” facts have deceived many people?

1. One drop of semen and ten drops of blood

There is a folk saying that one drop of semen and ten drops of blood are believed to be very valuable to men. Frequent sex will damage the yang energy and affect life. However, there is no scientific basis for this. In fact, semen is mostly water and contains only a small amount of amino acids and proteins. These nutrients can be obtained from food.

2. In vitro ejaculation is a good contraceptive method

After the sperm and egg combine, a fertilized egg is produced. The fertilized egg implants in the uterus and slowly develops into a fetus. Some people think that as long as semen is ejaculated outside the body during sex, unwanted pregnancy can be prevented. This statement is simply an insult to the IQ. In vitro ejaculation is when the penis is about to reach orgasm and the penis is immediately withdrawn, and then the semen is discharged from the body. The failure rate can reach more than 30%. In fact, during sex, part of the semen has already entered the female vagina. As long as there are energetic sperm in the semen, it will combine with the egg, causing the woman to become pregnant. Therefore, the contraceptive method of extracorporeal ejaculation is not reliable and may lead to delayed ejaculation, non-ejaculation or erectile dysfunction in men over a long period of time.

3. Frequent male masturbation will affect sexual performance

90% of men have the habit of masturbating to release sexual repression, but many men think it is shameful and believe that frequent masturbation will affect their sexual function in the future. In fact, after men enter puberty, their sexual organs gradually mature and they slowly begin to have sexual desire. In the absence of a sexual partner, masturbation can release and vent their sexual desire. After masturbating, the brain will continue to be in a state of excitement, making people temporarily fatigued. As long as the masturbation is controlled properly, it will not lead to neurasthenia. In addition, masturbation has almost no impact on the body, and it does not consume energy and physical strength. Generally, masturbation is enough once or twice a month. Do not overdo it.

4. A virgin will definitely bleed during her first sexual intercourse

Generally in TV dramas, whether a woman bleeds during her first sexual intercourse is used to determine whether she is a virgin. In their view, a woman will definitely bleed during her first sexual intercourse. If there is no bleeding, it means she is not a virgin. However, the truth of the matter is that 40% of women do not bleed during the first intercourse. Bleeding in the first intercourse is the result of a ruptured hymen. If the blood circulation of a woman's hymen is poor, there are only a few capillaries at the rupture site or the hymen has good elasticity, there will be no bleeding during the first sexual intercourse.

5. Dark color in women’s private parts indicates frequent sex

Some people think that the darker the color of a woman's private parts, the more frequent sex she has. The reason is that repeated sexual friction will cause melanin to accumulate, but this is not true. The number of melanocytes determines the depth of skin color. The distribution of pigment cells in various parts of the body is different. Some people originally secrete too much melanin in the vagina. In addition, the deepening of the color of the private parts is closely related to the sex hormones in the body, because the sex hormones will promote the production of melanin. After a woman enters puberty, the level of sex hormones in her body will continue to increase, causing the perineum to darken.

Warm reminder

Don’t fall into misunderstandings about sexual life. At the same time, you must master the correct method. It is recommended to wear condoms, which can not only prevent pregnancy, but also prevent sexually transmitted diseases.
