The frequency of sexual intercourse is the most intuitive and important manifestation of a couple's sexual life, but the frequency of sexual intercourse varies greatly in various aspects such as marital status, physical fitness, age of both parties, and sexual ability, and has always been in a dynamic state of change. Fifty or sixty years ago, the survey report by American sexologist Kinsey initially provided reference materials for the modern state of human life. This data shows that as age increases, the frequency of sexual activity shows a decreasing trend: approximately 3 times per week at the age of 20-30, 2 times per week at the age of 31-40, 1-2 times per week at the age of 41-50, and 1 time per week at the age of 51-55. However, there are significant individual differences in the frequency of modern human life.
For example, a survey on the frequency of sexual activity in modern Americans shows that 8% of men and 7% of women have sex more than 4 times a week, 26% of men and 30% of women have sex 2-3 times a week, 16% of men and 18% of women have sex several times a year, and 14% of men and 10% of women had almost no sexual activity in the year before the survey. The frequency of sexual activity between couples, just as important as age, is the influence of marriage age. According to data provided by renowned sexologist Maestros, the frequency of sexual activity among newlyweds surveyed was 14.8 times per month in the first year, followed by a decrease year by year, with 12.2 times in the second year, 9 times per month in the fourth year, and 6.3 times in the sixth year.
Many sexologists point out that the frequency of sexual intercourse between couples decreases with the increase of marriage age, while there are also reports that the frequency of sexual activity reaches its peak after 15-20 years of marriage. At present, many surveys and general opinions suggest that education level, occupational category, and religious beliefs have no significant impact on the frequency of sexual activity between couples. According to a survey of 6210 urban residents and 1392 rural residents in China, urban couples have sex 4.66 times a month, while rural couples have sex 5.43 times a month. In this regard, Chinese people seem to be no different from foreign countries.
