How can I deal with feeling a bit impotent?

Patient's question:

Detailed medical condition and consultation purpose: I developed the habit of masturbation around the age of 22, and until this year, I quit it a few months ago. Recently, I injured my waist due to an accident while driving and went to the hospital for a check-up. The doctor, who is a friend of mine, mentioned that I had a bit of white discharge after urination and recommended I get tested. The results showed slight prostatitis, with white blood cells at 2; everything else was fine. He said it was caused by masturbation. I used to masturbate quite frequently, almost daily. This year, after the waist injury, I felt a bit of impotence. When I was with my girlfriend and tried to have sex, I could get an erection, but it quickly went limp before any sexual intercourse took place. A few times, it was completely

Doctor's answer:

Problem Analysis: Impotence can be recovered, and you can also adopt the following methods to be helpful:
1. Tracking Imagination Method: Imagine yourself and your wife in a passionate love scenario, as well as the joyful moments of your first sexual success, to help you relax and enter the role.
2. Physical and Mental Adjustment Method: Change unhealthy lifestyles and negative mindsets. Excessive drinking, overwork, poor hygiene, and irritability can lead to psychosomatic diseases; a regular lifestyle, harmonious interpersonal relationships, and a balanced approach to fame and fortune contribute to physical and mental health, fostering a harmonious family life.
3. Massage Relaxation Method: Stimulating specific parts of the body can regulate the activity of internal organs. Mild, continuous stimulation has an inhibitory effect on the central nervous system and an excitatory effect on the peripheral nervous system; rapid, intense, and short bursts of stimulation can excite both the central and peripheral nervous systems. Since massage can regulate the nervous system, it can alleviate mental fatigue.
Suggestions:
1. Abstain from masturbation.
2. Focus your attention on studies and work.
3. Cultivate healthy hobbies and interests, and channel excessive sexual energy through a rich and varied leisure life.
4. Develop a correct understanding of the dangers of excessive masturbation to free yourself from the mental pressure of harmful self-gratification.
