Masturbation is simply a form of sexual catharsis that has many benefits when done correctly. It can help people gain a sense of well-being, solace, and have wonderful orgasms, and it can also help release stress and balance emotions. However, improper masturbation, that is, excessive masturbation, masturbation before and after not clean, the danger should not be underestimated. Although masturbation is difficult to be accepted generously, it is also difficult to be rejected outright by sexually mature individuals. But as the old saying goes, you have to do everything in moderation. If you do not masturbate properly, i.e. masturbate excessively, masturbate before and after not clean, then the danger should not be underestimated! The actual fact is that you will find a lot of people who are not able to get a good deal of money from the internet. This is a case of excessive masturbation, which may increase the mental burden, cause depression, memory loss, difficulty concentrating, and in severe cases, insomnia, dreaminess, palpitations, and other symptoms. Among them, men can be caused by frequent ejaculation, resulting in a situation where the quality of semen decreases, and women can be caused by an increased stimulation threshold, resulting in a situation where it is difficult to reach orgasm during intercourse; not clean before and after masturbation: when women masturbate with their hands or tools, they do not wash their hands, tools or pubic area in advance, which makes it difficult to ensure the invasion of foreign pathogens, such as bacteria, mycobacteria and mycoplasma, disrupting the balance of vaginal flora and inducing vaginitis. Secondly, because women have a shorter urethra and a more special physiological structure, not paying attention to hygiene during masturbation can also easily lead to urinary tract infections. These hazards can be completely avoided by washing carefully before and after masturbation! The conclusion is that masturbation is harmless, as long as you keep it moderate and pay attention to cleanliness, even if you are single, you can also experience sexual pleasure through masturbation.
