There are four types of duration of sexual intercourse between men and women

Some people divide the changes in the length of sex time throughout life into four types:

1 Gradually prolongs with age, accounting for about 20%.

As age increases, the ability to control ejaculation continues to improve. As age increases, the excitability of the erection center gradually decreases, while the erection value continues to increase. Correspondingly, the excitability of the ejaculation center also continues to decrease, while the ejaculation value continues to increase. In addition, it may also be because the couple can communicate fully and effectively, ultimately achieving tacit cooperation and harmonious happiness.

2 With the increase of age, the duration of sexual intercourse continues to gradually shorten, accounting for about 20%.

This shortening will become more obvious after middle age. On the one hand, it is related to the gradual decline of physical strength and energy. On the other hand, it is also greatly affected by their psychological and mental factors. They may pay too much attention to the local and mild changes in their physical and sexual functions, thus making the physiological changes worse and becoming complete and obvious changes.

3 It first lengthens with age and then gradually shortens after middle age, also accounting for about 20%.

This shortening often reflects a decrease in erectile ability rather than a decrease in the ability to control ejaculation.

4 For the remaining 40%, the duration of sexual intercourse remains unchanged throughout their lives.

This may be related to the fact that their neural reflex types are relatively stable. So there has never been any obvious fluctuation in sex life over the decades.

The harmony and happiness of a couple's sexual life depends to a large extent not only on the man's erectile ability and the duration of sexual intercourse, but more importantly on the degree of his mastery of sexual skills and his overall understanding of sex. This involves what we emphasize on improving sexual quality. Sexual function is innate, and a male fetus can have an erection in the womb. However, mastering sexual skills is not something that can be learned without a teacher. It must be learned, and one must receive sufficient and scientific sex education. Sex education during adolescence alone is not enough for a person's sexual health throughout their life. They must also continue to receive adult sex education. It would be tragic if the level of sex education for all the people was limited to the adolescent level. It would inevitably lead to sexual blindness and sexual disharmony among many adults, ultimately causing sexual dysfunction or leading to the breakdown of marriage.
