      How often is the most appropriate time to have sex? This is probably a question that many people have had. In this regard, American scholars have summarized a "sex frequency formula" based on the influence of age factors on sexual ability-sex frequency = the first digit of age × 9. That is, multiply the tens digit of your age by 9. The tens digit of the product is the number of days a sexual cycle lasts, and the units digit is the frequency of sexual intercourse that you should have.

      According to the United States' female healthy magazine reports that this formula is suitable for adults over the age of 20. For example, for a 25-year-old person, his or her sexual intercourse formula is 2×9=18. 18 is a combination of 10 and 8. That is to say, the appropriate sexual intercourse frequency for him or her is 8 sexual intercourses in 10 days. Frequency exceeding this is too frequent and may cause physical discomfort.

      For this formula, Tsinghua University Yuquan Hospital Yang Dazhong from the Department of Sexual Medicine said that although the formula is relatively rough, the calculated results are scientific and can be used as a reference. Sexual life content includes masturbation, sex Dream , caressing and other methods, they can bring orgasm experience and should also be included in the frequency of sexual intercourse. In real life, the frequency of sex between couples is closely related to their relationship, life, work, and health. The most appropriate frequency is the state in which both parties feel the most harmonious.
