There is no authoritative data to show how long the interval between sex life is normal, generally if the couple’s body if there is no weakness, discomfort and other symptoms, can be combined with their own state to adjust the frequency of sex life.
Due to individual differences, it is impossible to specify how long the interval between sex lives is normal. Usually, couples can adjust the frequency of sexual life by themselves if they are physically able to do so, and there is no fixed value. However, if after a sexual intercourse, both husband and wife appear tired, discomfort and other symptoms, should adjust the frequency of sexual intercourse, so as not to overwork, damage to the health of the body.
If both husband and wife have abnormal discomfort after sex, they should go to the hospital to clarify the cause of the disease.
