What are the reasons for short sexual duration, premature ejaculation, etc.?

Patient's question:

Short sexual duration, premature ejaculation, feeling tired, lower back pain, partner not enjoying it, not as hard

Doctor's answer:

Short sexual intercourse duration is related to excessive foreskin. After circumcision, the exposed glans will increase its sensitivity. It is recommended that you undergo circumcision and avoid overworking. Exercise moderately. Maintain a regular sexual life. Quit bad sexual habits. Premature ejaculation is a difficult condition to recover from. Friends with this condition should maintain a positive mindset and face it with optimism, as only this can boost their confidence in combating premature ejaculation.
