Sex life is short, hardness is not enough, is it premature ejaculation?

Patient's question:

Sexual intercourse is short, not enough hardness

Doctor's answer:

Hello, this may be caused by kidney deficiency, which is generally related to frequent sexual activity or masturbation.
Guidelines:
You can take some kidney-tonifying medications, such as Wuzi Yanzong Wan, and also include more kidney-nourishing foods in your diet. Engage in appropriate exercise to enhance kidney function. Sexual activity should be moderate, with no more than 2 times per week.
