The woman who overindulges in sex is harmful but not beneficial because excessive sex often causes the following hazards: 1. it can cause mental depression, self-fatigue, daily lethargy, and insomnia. 2. it may cause inflammation of the reproductive tract, as excessive indulgence can lead to minor damage to the cervical mucosa, and the invasion of pathogenic bacteria from the damaged fissure can cause chronic inflammation of the cervix. Clinically, it causes an increase in vaginal discharge, yellowish in color, and particularly thick discharge, and pain in the lumbosacral region. In severe cases, retrograde infection of pathogenic bacteria may cause inflammation of the pelvic cavity, resulting in recurrent lower abdominal pain, and even infertility and sterility.
