The amount of sexual activity is different for each individual. Generally speaking, the frequency varies according to ethnicity, different regions, different social and cultural backgrounds, as well as individual age, health and psychological state. Some newlyweds, on their wedding night, have intercourse 4-5 times in a row, and even have sex during the day, but it should be appropriately moderated and not excessive. Some people survey, the number of men’s sex life generally decreases with age, during the 22-25 years old, 3 times a week; 32-35 years old, 2 times a week; in the 41-45 years old, down to 1 time a week. Of course, this is only an average. Each age group varies greatly, with some as many as several times a day and others as few as once a month. So you can’t judge whether intercourse is moderate just by the frequency of intercourse. In terms of physiology alone, then both men and women, regardless of age, in the generation of sexual excitement, as long as it is not forced, and there is no uncomfortable feeling, then you can have sex, there is no need to consider the last time how long. The so-called reluctance, women is to submit to the sexual requirements of the male partner; in men is: originally not so want to sex, but by reading pornographic books or videos to “stimulate” themselves, or even forced masturbation in order to put into sex life. This is quite harmful. The reason is that after each ejaculation, the male will no longer have a sexual response for a short or long period of time. It is a natural protection for men. If you force yourself to go into sex at this time, it is considered to destroy the protection of their own period of inactivity, which is certainly harmful to the body. A lot of infertility patients are often overwhelmed by the frequency of sex, because some doctors let them have more sex, while others limit it, how to do it more effectively? The objective criterion for measuring the appropriateness of the frequency of sex is whether or not you are refreshed and happy the next morning. If the following conditions occur on the second day or within a few days after sexual intercourse, and no other reason can be found, it can be considered excessive and should be moderated and the interval between sexual intercourse should be extended appropriately. It is worth mentioning that men are more likely to indulge themselves and have sex too often. In some men’s view, the more sexual intercourse can show the strength and dignity of men; perhaps, they are not clearly aware of this, just feel that they should do their best to meet the sexual requirements of their wives. Therefore, when they have gotten pleasure from sex, they will continue to strengthen their sexual consciousness, attempting to get an erection again in the shortest possible time, with the power of the will to support the tired and ready body for sex, which is undoubtedly a great danger to physical and mental health.
