Too much sex for women can bring various hazards to women, such as: firstly, too much sex can lead to vaginal relaxation, which can affect the quality of sex life. Secondly, it increases the risk of vaginitis, cervicitis and other gynecological diseases and leads to increased leucorrhea and odor. Finally, there is a large amount of physical energy consumed when having sex, if sex is too frequent will lead to a decrease in body resistance, resulting in poor spirit, fatigue and other symptoms. So it is recommended that in ordinary life sex must be moderate, not too frequent. Generally twenty to thirty years old women three to four times a week, between thirty and forty years old women two to three times a week sex is more appropriate, forty years old women once or twice a week is better.
