It is worth pointing out that men have sex all their lives, so don't eliminate themselves. Women want to stay in the best condition for a long time, but also need to rely on professional private parts maintenance.

According to the influence law of age factors on sexual ability, authoritative experts summed up a "sexual frequency formula"-sexual frequency = the first digit of age ×9, that is, multiply the ten digits of a person's age by 9, and the product of the ten digits will be the number of days that a sexual cycle lasts, and the unit will be the appropriate sexual frequency. For example, men in their thirties, 3×9=27, should have sex 7 times in 20 days, which is about 3 days 1 time, without affecting their health and working conditions. This formula applies to adults over the age of 20.

Stephen, a famous sexologist, said: "The sexual life between husband and wife should be combined with each other's actual situation, and the frequency should be controlled without affecting health. It can be said that it is not too much to be tired the next day after sex. However, some elderly women or women who have sex too often admit that they often feel dry in their private parts or make some embarrassing noises during sex, which makes them want to escape from sex. In fact, this is the performance of aging private parts, which should be properly maintained.
