Under normal circumstances, a reasonable sex time should be based on no worries after getting up the next day, no back pain or back pain. This is because back pain after sex is actually a kind of self-protection measure for the human body, which is intended to remind men to reduce their sex time.
Men's sex interval calculation method:
The number of days between sexes for men under the age of 50 is based on the tenth digit of age. For example, a 30-39-year-old man can love at one time for 3 days.
50 to 59 years old sex between days is the tens of age multiplied by 1.5, that is (5 × 1.5 = 7.5) 7 to 8 days.
The number of days between sexes over 60 years of age should be the tens of age multiplied by 2, which is (6 × 2 = 12) about 12 days. Remind that the calculation method is the normal male sex interval, excluding men with chronic diseases.
Netizen:
I am 8 times a night at the highest time, and do not wait for 20-40 minutes each time, but it will not work properly on the second day, generally 3-4 times a night is possible, not 3-4 times a night, if it is continuous every night 3-4 times is also very difficult. Orgasm is easy for men and women to be familiar with and cooperate well. My wife basically can play her to orgasm every time, other people do n’t know.
Ordinary women can't reach orgasm in their lifetime. If they can reach orgasm, it is best not to come down. It is always best to be at orgasm. Seven times, I still did n’t reach the highest level. It ’s really high when you do n’t know if it is down.
Normally once a day is the best. If there are too many people in the long term, they will lose their energy, fatigue and weakness, and their backs and legs will soften. As they grow older, they will gradually decline. Therefore, you should cherish your body and keep it as normal as possible.
