A survey conducted by sexologists found that 95% of adult men admit to having masturbated and 60% of women admit to having masturbated. This shows that masturbation is a widespread sexual behavior and sexual physiological phenomenon among adolescents. Masturbation in adolescent boys and girls is a sexual activity that accompanies normal sexual development. Sexologists have conducted a lot of comparative studies on people who masturbate and those who do not, and confirmed that masturbation is not associated with psychiatric disorders such as neurosis, schizophrenia, personality disorders, depression, mental retardation, and psychosomatic diseases such as gastroduodenal ulcer, bronchial asthma, hypertension, and coronary heart disease. Studies have also shown that the presence or absence of masturbation is not associated with later intelligence, achievement, social adaptability, or sexual function. There is no scientific basis for the claim that masturbation can lead to kidney deficiency in men and women or lead to penis, testicles shrinkage and deformation and male prostatitis or premature ejaculation and impotence. Of course, due to masturbation does not pay attention to hygiene and lead to bacterial infection caused by inflammatory diseases such as prostatitis; or masturbation incorrect way and some problems (some men will insert everyday objects into the penis, may slip into the urethra, causing injury. If a woman masturbates, if she puts inappropriate items into her body, it may also cause injury) or if a man is used to masturbating in a hurry and develops the habit of ejaculating too early, thus forming a conditioned reflex that leads to premature ejaculation impotence is possible. This is not a problem brought about by masturbation itself, but by the lack of attention to personal hygiene during masturbation and incorrect masturbation methods. On the other hand, masturbation can be a way to treat premature ejaculation. The way to do this is to stop immediately when you are about to ejaculate. When the feeling has passed, you can continue and repeat it many times, you can learn to control the time, which will also help your sex life in the future. You can also masturbate once before having sex to prevent premature ejaculation. This is as simple as having a snack before eating, so that you won’t wolf down your food during dinner. It is scientifically proven that masturbation itself is harmless and does not cause disease. Moderate masturbation is not only harmless, but also has some benefits, for relieving sexual tension, relaxing oneself and relieving psychological stress. However, sexologists conducted a survey on college students in the 1980s and found that 43% of male college students felt doubtful and distressed about ejaculation, only 20% thought it was a normal phenomenon, and the rest still retained a partial ambiguous understanding of it. Because of the incorrect understanding of masturbation, some young people are frightened and finally suffer from biblical disorder, depression, and some even commit suicide for this reason. Many people feel psychologically guilty about masturbation or blame masturbation for their academic difficulties and relationship difficulties. Today’s sex scientists categorically reject the fallacy that “masturbation is harmful” and believe that the so-called sin of masturbation, if it exists at all, is the result of the absurdly horrific propaganda that “masturbation is harmful”. The more representative view is found in the American Psychiatric Manual, published a few years ago, which states: “Masturbation is a standard sexual behavior. More and more sex scientists believe that the masturbation horror is artificial and that the connection between masturbation and psychosis is purely illusory, and that the only way to link it is to include masturbation horror as a form of psychophobia.” Masturbation itself is harmless, but the consequences it brings to people cannot be denied and cannot be ignored, but they are not caused by masturbation itself, but by the misconceptions surrounding masturbation and people’s ignorance of sexual medicine. Some young people can not control themselves to stop masturbation, but also in a serious self-blame, masturbation “hate to the bone”, “fear of the devil”, and thus have a neurasthenia or other psychological diseases. These are human fears at work, “Masturbation is a standard sexual behavior. The reason it becomes a problem is that masturbation is accompanied by a feeling of guilt and inner anxiety and fear, and therefore suffers all kinds of consequences”.
