Does masturbation affect sexual function?

Patient's question:

With over a decade of sexual experience, I've noticed that when I'm intimate with my girlfriend, my erection isn't as firm as it used to be, and I reach climax quite easily. It feels like my sexual stamina has decreased. What should I do?

Doctor's answer:

Appropriate sexual activity is not harmful to physical health, but long-term sexual activity can lead to the following adverse effects: 1. Premature ejaculation 2. Anejaculation
Thus, when they engage in normal sexual activity, due to the inability to experience the intense friction during intercourse, they may again suffer from anejaculation and fail to enjoy the pleasure of normal sexual activity.
For male patients, timely treatment can reduce the incidence of the disease. If left untreated, it can affect their health condition. Therefore, patients should take medication promptly and maintain a regular lifestyle in daily life, avoiding prolonged sitting.
