The formula for sex frequency published by American sexologists:
Sex frequency = the first digit of age × 9
For example, for a 20-year-old boy, his sex frequency formula is 2 × 9 = 18! 18 is a combination of 1 and 8, so the suitable sex frequency for him is 8 times in 10 days! The same applies to those aged 30, 40, and 50!
Everyone should remember that the most important thing in sex life is to completely "release" the accumulated sexual impulse energy, which is a healthy and high-quality sex life. Simply pursuing the number of sexual intercourses to satisfy one's desire for conquest and self-confidence will ultimately only harm one's health.
