How to treat short Yin meridians and premature ejaculation

Patient's question:

Some fatigue in the body

Doctor's answer:

Common causes of premature ejaculation are related to prostatitis or lack of sexual experience, and it can also be seen in cases of excessive foreskin. It is not related to the length or size of the penis.
Advice: For normal adult males, an erection shorter than 4 centimeters is considered normal. Treatment can be achieved by adjusting sexual behavior.
