Masturbation is the stimulation of the sexual organs to achieve sexual pleasure and orgasm. In fact, it is an effective method of “ejaculation” used by young people and even adults. Whether male or female, it can happen. There are more men than women who have the habit of masturbating, and the results of a survey by foreign medical doctors showed that about 80% of men and more than 30% of women have masturbated. ”The idea that masturbation is harmful has been popular for centuries, however, some people believe that masturbation is beneficial and that it is a reasonable way to relieve sexual tension during adolescence as a result of the development of sexual psychology and increased sexual awareness. The Japanese used to call masturbation “masturbation” and use it as an indicator of psychosexual development, so they believe that occasional masturbation is not harmful. However, long-term frequent masturbation is harmful to the human body. This is because frequent masturbation can make the sexual control nervous system in a state of tension, and over time it can cause impotence as it shifts from excitement to inhibition. The actual “threshold” of sexual stimulation needed by the sexual organs can be increased by masturbation, and after marriage, when the sexual stimulation of conjugal life does not reach its threshold, there can be “no ejaculation” symptoms. In short, long-term masturbation has the following harmful effects: 1, easy to induce impotence or non-ejaculation in men, women do not appear orgasm. 2, so that the sexual organs are extensive chronic congestion, will induce men aseptic prostatitis, or women pelvic bruising, resulting in back pain, lower body swelling. The seriousness of the situation can make the brain overexcited and cause neurasthenia. It can be seen that occasional masturbation is harmless, but long-term frequent masturbation has an impact on sexual life and fertility. The occasional masturbator does not have to carry the burden of thought for this, but long-term frequent masturbators must quit.
