Sex, like sleep, is one of human instincts, and it is also a physiological and psychological need. Therefore, as long as they are normal people, everyone has sexual desire. But some people misunderstand that sex life is harmful to longevity. As a result, some elderly people have normal sexual function, but they have stopped having sex. This abstinence is not good for both husband and wife. Sexual life is an important part of human life, which is indispensable to people's physical and mental health, longevity, conjugal love and family happiness.

Traditional Chinese medicine has always believed that abstinence is not conducive to physical and mental health. Ancient health book "Sanyuan Life-prolonging Counselor's Book". "My Desire is Endless" said: "The Yellow Emperor said: Yin and Yang are the Tao, and Yin and Yang are diseases. He also said: I don't know these two. If there is no autumn in spring and no summer in winter, it is called holiness. Saints are always harmonious, but being naive is more expensive than keeping secrets. " This means that the unity of opposites between Yin and Yang is a universal law of nature. Under normal circumstances, yin and yang are in balance, and the human body must maintain balance to ensure health. When yin and yang rise and fall, they will get sick. Moderate sex life is a means to reconcile yin and yang. Human kidney essence is constantly produced due to the nutrition of Houtianshui Valley. Sufficient kidney essence will help the heart fire, which will "burn in the fire" and produce sexual requirements. Therefore, sexual intercourse is neither essential nor frequent. If appropriate, it is good for health.

Traditional Chinese medicine also believes that long-term abstinence will lead to "blood stasis and tendon dystrophy", but it is "weak and useless". It shows that the result of long-term abstinence will make it lose its sexual function forever. Because abstinence destroys the balance of yin and yang and suppresses people's sexual instinct, the sexual desire gathered by the human body can not be released, but it will bring harm to people's spirit and body. Alice, an American sexologist, said: "The result of abstinence will cause a small-scale commotion and make people feel uncomfortable." Modern sexology and medical experts masters and Johnson's research also confirmed this point. Because the sexual tension that drives sexual desire is a kind of biological energy, it obeys the law of conservation of energy and can only be transformed, not disappeared. Normal and moderate sexual life can realize sexual desire and release sexual tension. When sexual desire is not vented for a long time, "sexual tension" will occur.
