What are the harms of frequent masturbation?

Patient's question:

Detailed medical condition and consultation purpose: Last year, I went to a video rental store with him, and we watched pornographic movies, but it was our first time. A year later, he told me that since watching the pornographic movies, he has been masturbating frequently, and it has been going on for a year.

Doctor's answer:

Hello, the dangers and consequences of masturbation
1. Masturbation is a severely damaging act to the body and spirit. The "essence" consumed by masturbation is the life-giving source and blood-creating essence stored in the kidneys, which are connected to the marrow and brain marrow. Excessive consumption of essence can lead to marrow cavities, of brain marrow, premature aging and early death of life, and extreme physical weakness is merely a secondary manifestation.
2. The human body is nourished by blood and qi, which come from food. Unconsumed blood and qi transform into essence during deep sleep and are stored in the kidneys, sealed within the bones for future needs. If consumption is low and savings are high, it is the guarantee of longevity and health; if consumption is high and savings are low, it is the premise of aging and a short life. Both masturbation and sexual behavior manifest as the consumption of essence, and the excessive accumulation of this consumption means a decline in quality of life and an early end to the life journey.
3. Masturbation not only damages the body's vitality but also harms the emotions, causing mental fatigue, weak will, indecisiveness, procrastination, irritability, and suspicion and fear. When facing matters, one may either rush forward or retreat, lacking patience and perseverance, as well as confidence and courage to succeed. All of these are the result of insufficient essence unable to transform into qi.
4. Masturbation also affects intelligence. Long-term masturbation can significantly damage memory and thinking ability, with a lack of effort in learning and a rapid decline in academic performance being the most obvious manifestations. This is the result of insufficient essence unable to transform into qi, and qi unable to transform into spirit.
5. The uncontrolled and rampant nature of masturbation is related to the misguidance of Western medical theories. Middle school physiology and health education
