Sex is a normal biological need for adults. So, how many times a month is normal? Clinically, it is generally accepted that the frequency of sex decreases with age. Usually: 20~30 years old, 7~8 times a month is normal. Even some young people 3 ~ 4 times a week, or 1 time a day, as long as no physical discomfort after sex, does not affect the next day’s work, study and life are normal; 30 ~ 40 years old, 4 ~ 8 times a month is also normal, some people may be due to work, family and other aspects of the pressure is relatively large, the frequency of sex will decline, sometimes 1-2 times a week, is also normal, but 1 It is best not to exceed 10 times a month; 40 to 50 years old, a month of sex 2 to 5 times in fact, even if it is normal. There are also studies that say that it is normal for women to have sex about 4~6 times a month. This age group, the frequency of sexual life at least 1 time a week; 50 ~ 60 years old, 2 ~ 3 times a month is normal. 50 years old and older men, with the decline of physical fitness, sexual function will have different degrees of decay, the frequency of sexual life to ensure that the frequency of 1 time every two weeks, the maintenance of the sexual function of the elderly population, health care, including the maintenance of the relationship between husband and wife is a necessary standard; and for 60 years old For older people above 60 years old, if they are healthy and not accompanied by other serious diseases, 1~2 times a month is enough, but preferably not more than 2 times. Is the sex formula credible? American scholars have concluded a “sex frequency formula” based on the impact of age on sexual ability, that is, the frequency of sex = age decimal x 9, the product of the decimal is a sex cycle, and the single digit is the frequency of sex should be. This formula, applicable to adults over 20 years old. If a 30-year-old person, his (her) sex formula is 3 × 9 = 27, that is, his (her) sex frequency for 20 days to have sex 7 times, more than a this frequency is too frequent, may cause physical discomfort. Although the formula is relatively rough, but the calculated results have a certain scientific nature, can be used as a reference. In general, the frequency of sex life has a very large individual differences, in addition to age, physical or psychological state, the frequency of sex life will be different. Therefore, there is no standard range of how many times a month you have sex, and you can’t generalize. So, how to determine whether the frequency of their sexual life is appropriate? Is there an ideal frequency of sex in the end? In fact, to determine whether the number of sexual life is moderate, but also to see the performance after sex. If you don’t feel tired after sex, but full of energy, physical and mental pleasure, full of energy, this is the appropriate performance; and if after sex there is a lack of energy, weakness, tiredness and discomfort, and even affect the next day’s work and life, it means that sex is too frequent, too much, should be moderated. And the latest issue of the U.S. magazine “Pleasure” article pointed out: the most ideal frequency of sex, is the couple agreed on sex, and not stuck to a fixed pattern. References: [1] Anonymous.
