The question that children are most interested in sex life is probably the frequency of sex life. After marriage, people can't help asking, how many times is sexual intercourse appropriate? It's a long story. Generally speaking, couples aged 20 to 30, 3 to 5 times a week; 3 1 ~ 40-year-old couple, 3 ~ 4 times a week; 4 1 ~ 50-year-old couple, 2 ~ 3 times a week; 51~ couples aged 55, once a week 1 ~ 2 times; Couples aged 56 to 60, average weekly 1 time. Generally speaking, the number of sexual intercourse is basically inversely proportional to age, that is, the older you are, the less the number of sexual intercourse is. Most readers are aware of these situations. Every couple is a unique combination, and their situation is also very different. There are individual differences in physiological differences between men and women, even in the same sex. There are many differences between people in age, personality, physique and occupation, so the number of sexual intercourse between different couples varies greatly. Due to the influence of climate, environment, disease and work, even the number of sexual intercourse of the same couple often changes. The number of times mentioned above is only approximate statistics, and it is not necessarily abnormal to be higher or lower than these figures. People are understandably worried about sex. Many newspapers and books list that many emperors in ancient times were addicted to physical injuries and rarely lived to be over 80 years old. But what is "lust"? There is no doubt that many ancient emperors indulged in physical injury and loss of life. For lust, these emperors not only had excessive sexual intercourse, but also sought and abused aphrodisiac tonics in various ways, and these drugs containing androgen or lead often damaged sexual function and health. Therefore, some newspapers often use these materials to scare people intentionally or unintentionally when they move out of the emperor to explain the problem. If both husband and wife are healthy, sexually active and have no discomfort after sex, then the frequency of sexual life is much higher than the general statistics, which is not necessarily called "indulgence" or "harmful". Because under normal circumstances, most of the sexual life between husband and wife will be naturally adjusted. This theory of "indulgence hurts the body" unilaterally regards sex as a tool to preserve health and prolong life. Of course, a happy and harmonious sexual life plays a very important role in couples' physical and mental health and longevity, but this refers to paying attention to sexual health care and health preservation and disease prevention, including using various sexual skills and correctly using the means of complementary yin and yang. Under the influence of feudal superstition, one-way "collecting yin and nourishing yang" replaced "yin and yang complement" and "consolidating essence" replaced "cherishing essence". In this way, it is the correct way to "solidify" and "return" the essence in men without ejaculation or even sexual life, instead of harmonious and normal sexual life to achieve the purpose of health care. The fallacies such as "one drop of essence, ten drops of blood", "overwork is fatal" and "the loss of essence is harmful to the health" also came into being. This kind of sexual ignorance has ruled our people for hundreds of years. Many newspapers and books mentioned: "The principle is that neither side will feel tired the next day in after making love. If there is heavy head and back pain, shortness of breath or loss of appetite, it means that sexual life is too frequent and should be adjusted in time. " This formulation is generally correct. But it is not absolute. Feeling tired after sex is often caused by excitement. After playing for a long time, I have less rest time, and I will feel tired the next day, but this is not necessarily the number of sexual intercourse itself, but the time is not well mastered. As long as the schedule is adjusted, it is not necessarily caused by excessive sexual intercourse. On the other hand, if the frequency of sexual intercourse is high, it will be exaggerated, which will not only help, but will increase psychological pressure and inhibit sexual desire. In the eyes of many men, the more frequent sexual intercourse, the more they can prove their sexual ability and show their "glory". They try their best to meet their wives' demands, hoping to prove their strength from sexual excitement. Their repeated sexual intercourse in one night is not so much sexual pleasure as psychological satisfaction. They can only take comfort from such a glorious history. On the contrary, it reduces the quality of their sexual life. Because, the shorter the interval between two sexual intercourse, the less semen is injected, and the more times it is repeated in a short time, it may cause no ejaculation at all, and the sexual pleasure will further decline. Harmonious and happy sex life means that both men and women get sexual pleasure and psychological satisfaction, not the pursuit of sexual intercourse itself. Some young and middle-aged couples only have sex three or two times a week, but both sides are very satisfied. It should also be said that these couples have a harmonious sexual life. Men also pursue the number of sexual intercourse, because they have some misunderstandings about it and think that the more women ask, the better. In fact, this view is very incomplete. Generally speaking, although a woman can have multiple orgasms during one or more sexual intercourse, she often gets more pleasure from the first orgasm. Endless stimulation will also reduce a woman's sensitivity. Some women ask for the second or even the third sexual intercourse, and often the first one or two sexual intercourse failed to reach a satisfactory orgasm, so they hope to get compensation in the second or even the third sexual intercourse. There are also some men who think that women have never refused to ask for sex every time, mistakenly thinking that women have such needs, but they don't know that these women are fulfilling their obligations, and how many times their husbands need it, they will cooperate. When their obligations are fulfilled, their hearts will be relieved. They think that after having sex with their husbands, their psychological security will increase and their doubts about their husbands will disappear. May people treat sex correctly and get pleasure and warmth from it.
