A reference formula formulated by foreign scholars according to the influence of age on sexual ability. When calculating, just multiply the ten digits of your age by 9, the ten digits of the product is the number of days that a sexual cycle lasts, and one digit is the appropriate frequency of sex.
(1) Take a 30-year-old man as an example, his sexual frequency should be "3× 9 = 27", that is, it is healthy to have sex seven times in 20 days, about every three days 1 time;
(2) The sexual frequency of people in their forties should be "4× 9 = 36", that is, they should have sex six times in 30 days, about every five days 1 time;
(3) People in their fifties are "5× 9 = 45", that is, they have sex five times in 40 days, about once every eight days.
However, after all, sexual life is an emotional matter, which is largely influenced by passion and physical strength. It's not enough to follow the rules, your feelings are the most important. ?
Sexual medicine research shows that the frequency of sexual intercourse in youth can often determine the frequency of sexual activity in middle-aged and elderly people. In other words, if he had more sexual life when he was young, his sexual needs would not be too low when he reached the middle-aged and elderly stage.
Three factors that determine the frequency of sex:?
(1) Emotion: Feeling for your partner is the decisive factor of sexual desire. If you are no longer interested in him or her, or even full of resentment, your sexual desire is definitely not high. ?
(2) Emotion: It is difficult for a depressed person who lives in stress and anxiety all the year round to be interested in sex, because sex needs passion and relaxation. ?
(3) Age: Research shows that the peak of male sexual desire is between 18-25 years old, and that of female is between 35-45 years old. Since then, sexual desire has gradually weakened.
