Medical history: 3 years

Doctor's answer:

Some people say that masturbation does not cause bad effects such as sexual dysfunction, but this is incorrect. Frequent masturbation constantly stimulates the nerves of the genital organs, just like drug addicts constantly taking drugs. When drug addicts first take drugs, they feel happy, but as they continue to use them, they realize that they don't feel as happy as before and need to keep increasing the dosage of the drug, over and over again, becoming increasingly unhappy and experiencing worsening memory and other cognitive impairments. Excessive masturbation stimulates the nerves of the genital organs, leading to dullness of the nerves. This not only affects the pleasure and duration of sexual life but also affects other nerves, causing the transmission of nerve signals to be slower than those who do not masturbate.
Repeated masturbation, with one sexual excitement after another, is similar to excessive sexual activity after marriage, weakening the body and causing symptoms such as tinnitus, palpitations, lower back pain, leg weakness, dizziness, memory loss, and declining intelligence. In severe cases, it may lead to frequent nocturnal emissions.
Those who frequently masturbate have abnormal sexual excitement and are very easily aroused. Frequent sexual urges and frequent ejaculation inevitably lead to nocturnal emissions, slippage of semen, and premature ejaculation. If the excitement shifts to inhibition, it may cause impotence or weak erections.
Those who frequently masturbate are highly sensitive to sexual stimulation, especially to the stimulation of ejaculation, making it easier for men to experience anejaculation after marriage.
