How long is it best for men and women to have sexual intercourse? Please follow 5 principles for harmonious sex

There is a formula for the frequency of harmonious sexual activity: 'Sexual frequency=the first digit of age' × 9”。

Experts point out that this formula should be used under two conditions: firstly, sexual activity must be carried out voluntarily by both parties; Secondly, it is important to acknowledge individual differences and adhere to the principle that both parties do not feel tired or uncomfortable after sexual activity. Under these two premises, this formula has its rationality, is suitable for China's national conditions, and can be used as a reference for most people.

This formula is applicable to people over the age of 20. What is the frequency of sexual activity for a person in their twenties (including those in their twenties)? Applying the formula, it is 2 × 9=18, 18 can be seen as a combination of 10 and 8, which means that the suitable sexual frequency for him is to have 8 sexual experiences within 10 days. And for a person in their thirties (including those in their thirties), their sexual formula is 3 × 9=27, which means he is suitable for having sex 7 times within 20 days. It seems that the frequency of sexual activity among public figures is no longer private. Is Andy Lau's sexual formula, which is already in his forties, 4 × 9=36, suitable for 6 sexual activities within 30 days?

Of course, the scientific nature of the data standards in this formula is still worth questioning, and it has once sparked a lot of skepticism. Some people believe that such formulas can only be used as entertainment. The benefits of harmonious sexual intercourse

Harmonious sexual life between couples can deepen each other's emotions and make families happy. Experts from Beijing Shuguang Men's Hospital pointed out that harmonious married life also has the following little-known health effects:

1、 A harmonious sexual life is beneficial for beauty. When you are excited, your whole body's blood rushes towards the surface of the skin, which can have a cleaning effect on the surface of the skin, effectively preventing skin aging.

2、 A harmonious sexual life is beneficial for eliminating tense emotions. Not only can it eliminate the physical tension during sexual intercourse between men and women, but it can also eliminate the emotional tension accumulated in busy daily life. Although daily physical exercise, such as running, doing exercises, swimming, etc., plays a crucial role in reducing emotional tension, sexual activity has its unique and irreplaceable effects.

3、 Harmonious sexual activity is beneficial for human breathing. During sexual activity, a person's heart rate accelerates, breathing becomes rapid, and blood circulation increases. Lack of sexual activity can have adverse effects on the heart. Someone conducted a survey comparing married and divorced men and found that there is a direct connection between coronary heart disease and sexual activity, and divorced men are more than twice as likely to suffer from heart disease as men with spouses.

4、 A harmonious sexual life can play a role in controlling weight. There used to be a belief that sexual activity consumed 500 calories at a time. This number may be slightly higher, as it depends on the length of sexual intercourse and the level of enthusiasm between the male and female partners. Generally speaking, a one-time activity can consume about the same amount of calories as a 15 minute bike ride. Although this is not a simple and absolute causal relationship, a harmonious sexual life can have a weight control effect, but it has its own reason.

5、 A harmonious sexual life can keep a man's prostate in good condition. Men often suffer from prostate infections due to prostate congestion, and regular sexual behavior can greatly help prevent this congestion.

6、 An active and harmonious sexual life has a certain cancer prevention effect.
