In one's life, youth and old age have very important turning points. That's 30. According to the statistics of sociologists, at the age of 30-35, couples are prone to conflict, and marriage breakdown is the most frequent. One of the biggest reasons is that 30-year-old men have quietly changed their performance.
Generally speaking, men's first strong sexual impulse occurs when they are 14-16 years old. When they are young, most of them think about sex. The first date, the first love, the first masturbation, the emergence of sexual orientation, the emergence of the ideal image of women, from the age of 17 to 19, the peak of sexual desire and impulse, from the age of 20, the strong sexual impulse gradually decreased, but the sexual function continued to strengthen. The diurnal mean sperm output (all sexual behaviors divided by the number of days in a year) is an objective measure of male function. The index continued to rise, reaching its peak at the age of 27 to 28. At this time, men will become more mature, he can better understand women's psychology, and have a relatively stable sexual relationship. In this age group, it is generally not easy to have extramarital sex.
When men reach the age of 30, the intensity of sexual desire begins to weaken, which gradually and slowly occurs. The age at which the decline begins varies from person to person. Some people peak at the age of 24 and begin to decline at the age of 25. Some people began to rise linearly at the age of 18 and gradually declined until the age of 35, but many men began to decline significantly at the age of 30. In this case, men generally do not pay much attention, do not feel a little energy decline, and also feel vigorous, but the sexual impulse is less than before, the sexual life is also less than before, and the sexual life is also less than before. It is also normal to be aware of the reduction of freshness in old couples. In fact, the function of men has quietly declined. As a wife, you should understand that the husband's sexual desire is a normal physiological change, and you must not be confused. On the contrary, wives must protect the dignity of men.
Men should never catch cold in seven parts of winter
Feet: experts pointed out that no matter the feet of men and women are the coldest part of the body, the feet are cold all over the body. The meridians of the kidney and spleen and stomach originate from the feet, but because the feet are farthest from the heart and the "distance" of blood flow is the longest, the blood supply is often insufficient. In winter, male friends should soak their feet with hot water every day to promote blood circulation throughout the body and keep the body warm.
Waist: the second area where men are afraid of cold in the waist. This part is the heart of the kidney. The kidney likes warm and cold. Men will make noise when they feel cold, the waist and knees are sore, impotent and premature ejaculation. Therefore, when the weather is cold, men must wear medium-length jackets and do not expose their waist.
