For what purpose do people engage in sexual activities? We hope that the discussion on this issue will bring beneficial results - change sexual concepts and enjoy sexual happiness. Food, sex, and sex. This famous saying by Master Meng Ke more than 2,000 years ago is still quoted by modern people today. Especially when fighting against sexual confinement, this sentence has become a sharp weapon. However, this sentence only tells a basic fact and lacks deeper thinking. Appetite and sexual desire are not only possessed by humans, but also by other animals, and they seem to be stronger than those of humans. But also as instincts, there are completely different differences between humans and animals. Animals act completely according to their instincts, but humans have to let their instincts be controlled by reason. If animals go to a banquet, they will eat to their heart's content. After thousands of years of civilized evolution, humans have formed their own unique social behavioral norms. Under normal circumstances, they would rather go hungry for a while than break them easily. From an instinctive point of view, food (eating) is to maintain life, and sex (mating) is to prolong life. If there is no fundamental difference between humans and other animals in the reflection of these two instincts in terms of food, they are quite different in terms of sex. Ordinary higher animals usually only have sexual desires during a certain period of the day, month or year, that is to say, they have a fixed estrus period, and after this specific time, they will never engage in indecent behavior. This is not the case for humans as the spirits of all things. Their estrus period disappears or is no longer obvious. Human beings' desire for sex has become all-weather - as long as the physical conditions and environment permit, after sexually mature people, the desire for sexual life can burst out and be realized at any time, regardless of day and night, day, month and season. Some people have counted that a couple who grow old together will have sex (sexual intercourse) nearly 3,000 times in their lifetime. If you respond to the call of a couple who want only one child, 2999 times of sex will not be purely for procreation like other animals. We still find out the answer to this question by comparing it with other animals. The lower the creature, the stronger the sexual instinct to pursue reproduction. Some lower-level organisms even have no substantive sexual activities at all, but complete their reproduction process through external sperm ejaculation and ovulation. On the contrary, the more advanced the animal, the larger its sexual sensitive zone, and the more it pursues sexual pleasure. This is especially true for humans. As early as the 19th century, Freud proposed the pleasure principle as a motivation for human sexual behavior. He wrote in "Introduction to Psychoanalysis": Our entire psychological activity seems to be determined to seek pleasure and avoid pain, and is automatically regulated by the pleasure principle. Freud believed that deep within the human psychological structure, there is an unconscious system that stores libido energy, that is, sexual instinct and its desire to vent (animal desires). This animalistic desire for sexual outlet only recognizes and follows one principle, that is, the principle of pleasure. Because in the release of energy (satisfaction of sexual desire), people will obtain happiness, it only experiences happiness. In order to obtain happiness, people are always eager to seek opportunities to release energy. In recent years, Freud's theory has received increasingly strong support and sufficient scientific evidence. Since the end of the 20th century, many revolutionary changes have taken place in the sexual concepts of human society: the arrival of post-industrial society has freed people from heavy mechanized labor and begun to have more leisure; more and more people no longer Threatened by poverty. These changes are also reflected in sex life. The human sexual theories of Freud and a large number of psychology and sexology masters have had an unparalleled impact on sexual morality. Relatively free expression of sexual needs has become a universal pursuit, sexual pleasure has become a new form of consumer goods, and the demanding sexual ethics of the past that favored natural principles and destroyed human desires have been dealt a devastating blow. The continuous improvement of contraceptive measures and tools enables people to enjoy sexual pleasure without having to worry about physical and social responsibilities. The women's liberation (feminism) movement that emerged along with social progress has brought about a general improvement in women's social status, increased their opportunities for education and economic independence, and their roles have gradually expanded beyond the family. Therefore, women's sexual activities have It greatly reduces the sense of attachment and subordination to men.... As a result, more and more people begin to accept the view that sexual pleasure is the direct purpose of sexual life, and that fully venting and enjoying sexual pleasure is the direct purpose of sexual life. Pursue. Biologically speaking, the pleasure principle is impeccable. The rich and keen sensory nerves of human sexual organs and the continuous expansion of the human body's sexually sensitive areas are fully explained from an anatomical perspective. Unfortunately, in real life, many people do not take this principle seriously once it is applied to specific sexual practices. What is the reason for this? We can only look for answers from the other two levels of sexual expression, the psychological and social levels. Since the Qing Dynasty, my country has formed a reproductive instrumental sexual behavior model based on the combination of yin and yang. Sex has always been regarded as a low-level instinctive life phenomenon. This model is specifically reflected in: 1. Sex must take place between a man and a woman: men and women are the traditional gender roles and the only recognized practitioners of sexual activity. In addition, other sexual activities, such as sexual activities between men and men, women and women (homosexuality), self-sexual activities (masturbation/ShouYin, sexual fantasies, sexual dreams), etc. are severely derogated. 2. Reproduction must be the ultimate goal: having children is not only to provide labor and property heirs for families engaged in agricultural production, but also to continue the bloodline of ancestors.

Sex has become a tool for carrying on the family line. 3. It must be limited to the scope of marriage: only sex within marriage is legal and moral. Extramarital sexual activities, such as premarital sex and extramarital affairs, are targets of social attack (or at least condemnation). 4. Love between husband and wife is the only way to adjust sexual life: sexual tools are called obscene tools, and pornographic materials are generally regarded as obscene. Such methods of sexual stimulation are despised by decent men. 5． Sexual life excludes children and the elderly: children who talk about sex or certain sexual behaviors are regarded as a scourge and a sign of no future; older people who engage in sex are regarded as immoral and disrespectful. 6． Sexual life can only be understood, not expressed, even between husband and wife. Under the above model, if sex life is to satisfy the needs of the other party, those with strong self-esteem or strong moral values ??will also feel better. But if sex is for pleasure, many people will suspect that they are too vulgar, too obscene, and too selfish. The pursuit of sexual pleasure can easily make people think of indulgent pleasure-seeking and a life of sensuality. And seeking pleasure and sensuality are precisely the actions of prodigal sons, which makes those who are truly noble and those who are falsely high-minded to criticize and avoid them: saying that we only have sex to pursue happiness, isn't this an insult to us? As a theory, the pleasure principle certainly has its merits. But as a sexual health doctor, I often advise those whose sexual lives are out of tune to happily accept this principle in sexual practice. If this is the case, many sexual problems will be easily solved, saving doctors a lot of trouble. For example, many couples are unwilling to talk about or try sexual intercourse positions because they think it is indecent; for another example, many women can accept their husbands’ direct sexual activities, but cannot tolerate unrelated sexual games. Some even think that this is hooliganism. Behavior. If you accept the hedonism principle, you will change your disgust and accept it happily. What is more meaningful is that the principle of pleasure can further accelerate the revolution of sexual concepts, thereby bringing about changes in the content of sexual life and promoting the harmony of sexual life. For example, according to the old sexual concept, women play a completely passive role, but according to the new sexual concept, women have to take action to strive for their own happiness. They can not only take the initiative and make requests to men, but also interact with men. Males also create in their sexual lives. It can be said that only when women participate in sexual activities on an equal basis with men, and only when men and women engage in sexual activities just for pleasure without other intentions and no additional conditions, can sexual life enter a truly ideal state. It can also be said that one of the important reasons why we have so many sexual and psychological issues that need to be discussed and why many people are troubled by so many sexual and psychological problems is that people have not yet truly understood and accepted the principle of hedonism. Not for anything else, but for yourself, for your own happiness. We hope that all couples who long for a happy sex life can use this sentence as a bedside motto.
