"Men are from Venus, women are from Mars", men and women have differences in physiological structure and thinking patterns, and are destined to be completely different species, which makes it difficult for men and women to understand each other in certain behaviors.

Today, let's talk about men first. There are always some commonalities in men, which make women incredible and puzzling. Xiaojiu specially selected 3 questions with the highest attention, which will definitely satisfy your great curiosity.

Myth 1: Why do men's pillows turn yellow so easily?

I believe that married women will be surprised to find that their husbands will "change color"!

Sleeping in the same bed, covering the same quilt, and using the same pillow, my own part is always clean, but my husband's pillow seems to have been splashed with oil, and it turns yellow and greasy. Sheets, and quilts that cover them, always turn yellow after a while.

The point is that even a man who loves cleanliness, loves cleanliness, and loves bathing can do this! Then this pot must not be carried by "not paying attention to hygiene". In fact, it is closely related to the physical characteristics of men.

From puberty to old age, men will continue to secrete male hormones, and the secretion amount is 20 to 30 times that of women. Excessive activity of male hormones will stimulate the secretion of sebaceous glands, and the sebum secreted contains unsaturated oily squalene. When exposed to air, this substance is oxidized to produce a polar brownish-yellow product, which is one of the reasons why men "discolor".

Another key factor is sweat. Sweat contains water, lactic acid, urea and other components, which can turn yellow after being discharged and oxidized.

The human body has sweat glands all over the body, sweating out almost all the time. Men have more developed sweat glands than women and sweat more. According to data published in the journal Experimental Physiology, men sweat twice as much as women with the same intensity of exercise.

Therefore, with the dual blessing of sebum and sweat, men themselves are more likely to become "dye pigments" than women, and the things they touch, such as pillows, clothes, sheets, towels, etc., will turn yellow over time.

Myth 2: Why do so many men fall asleep when they're done?

"A man is a lower body animal!" Many women will always come to this conclusion after in-depth contact with men.

In order to "get", men can turn black into white on the bed, and their speaking skills are up. but! After the incident, many men fell asleep and snored in seconds, which made women very hurt, suspecting that they were "tool people" and resentful.

In fact, there are biological reasons behind this. When a man is doing things, the sympathetic nerve is in a state of excitement, and the cerebral cortex plays an important role in attention, consciousness and perception sensitivity.

After the end, the brain turns off the command, the sympathetic nerves that were originally excited gradually decreased, and the hormone level decreased, which played a hypnotic effect. In addition, physiological activities such as increased heartbeat, increased blood pressure, and increased breathing during the work process will consume a lot of physical strength, making men tired. The feeling is even worse. The result of the combined effect of these factors is that men want to fall asleep.

However, this behavior does affect the relationship, making women feel neglected and neglected. It is recommended that men can hug their partners after doing things, simply communicate their feelings, and then fall asleep together.

Myth 3: Do men really "can't" after 30?

With the development of society, women's view of mate selection seems to have also changed. From the previous "look for an uncle, have a sense of security", now it is popular to love sisters and brothers, pursuing "little milk dogs" and "little wolf dogs", and often jokes. : Men are "useless" after the age of 30, and Xiao Xianrou is more "good".

Physiological needs do play an important role in marriage and love relationships, and one of the reasons for the increasing divorce rate is also because of discordant sex life. So, after the age of 30, does a man really "can't"?

Sadly, this is true.

Men begin to develop as they enter puberty, and their sexual function will gradually mature, which may last until the age of 30. With age, physical function declines, coupled with bad living habits, staying up late smoking and drinking, etc., will accelerate the decline of male ability.

Therefore, after the age of 30, male sexual function and libido will slowly decline, and by the age of 40, this change will be more obvious, and some men will also experience dysfunction, such as premature ejaculation, impotence, etc.

According to the NHSLS (United States) study, the incidence of premature ejaculation in people aged 30-39 is 32%, and the incidence in people aged 40-49 is 28%. The "Three Cities Epidemiological Survey of 2226 Men with ED" showed that the overall prevalence of ED (erectile dysfunction) was 26.1%, 24.5% between the ages of 31 and 40, and 40.2% over the age of 40.

However, male dysfunction has become a common male disease. If you find that you are not good, you can still be cured if you seek medical treatment and take measures in time. Taking premature ejaculation as an example, there are already special drugs for premature ejaculation, mainly oral drugs. Dapoxetine hydrochloride is a drug widely used in clinical practice, and it is also a drug approved for treatment in various countries. For example, Aitingjiu Dapoxetine Hydrochloride Tablets can act on the central nervous system of the human body. It can improve the control of the central nervous system on ejaculation by inhibiting sexual excitement, thereby prolonging the time.

Therefore, men, for their own happiness, don't be afraid to avoid doctors.
