What are the harms of female masturbation, but it did not use fingers to enter the vagina, only

Patient's question:

No

Doctor's answer:

Hello, it is not advisable to engage in masturbation for long periods, as it may lead to kidney deficiency or aseptic prostatitis. It is best to do it once a week and can be supplemented with a kidney-tonifying herbal medicine called You Gui Wan for treatment. The diet should be light and avoid spicy and irritating foods. Drink more water.
