Xiao Sun, a 26-year-old employee and single, came to the clinic 2 days ago with a sudden onset of painful urethra with yellow-white purulent discharge. During the communication, Xiao Sun was confused and said, “I have not been having sex, how can I have pus flowing from my urethra?” By further questioning the medical history, Xiaosun said he developed the symptoms after using a newly purchased masturbator. Masturbators are tools that mimic human physiology to a certain extent and are used for self sexual stimulation. With the development of society, everyone’s attitude towards sexual paraphernalia shows an increasingly open trend, in order to increase the sense of sexual stimulation, freshness, more and more people will use masturbators, as evidenced by its sales of up to ten billion yuan. For men, the most commonly used masturbators are “airplane cups”, “anti-real vagina”, “toy dolls” and so on. The material is usually made of soft synthetic resin or silicone, and inexpensive masturbators use sponge material. Due to the current lack of regulation of this market, there are some businesses with substandard product quality, of which disinfection is one of the most common problems. The reason for this is that the masturbator was contaminated with septic bacteria, which led to the onset of the disease. The actual fact that masturbation is a normal physiological phenomenon, just not excessive, there is no harm, with the help of masturbators is not wrong. But inappropriate masturbation is very likely to lead to disease. So we need to correctly understand masturbation and choose the right way: 1. Correctly understand that masturbation is a normal phenomenon, do not have a psychological burden. It can happen at all ages, and children’s unconscious playing with their genitals also belongs to masturbation. From adolescence, occasionally or at the instigation of others appeared to get orgasm for the purpose of masturbation, some people will be overwhelmed, indulge in it, this need to avoid. 2, do not over masturbate, moderate, occasional masturbation is not bad for the body. This is the case for several times a day, every day masturbation needs to be controlled; or masturbation after the body appears back pain, weakness, memory loss and other symptoms, you need to suspend to say goodbye to masturbation. 3, the use of masturbators, please buy regular merchants, or products with the guarantee of e-commerce. When using, fully use lubricant to reduce the possibility of damage to the penis from friction. It is best to use condoms to reduce genital infections brought on by products that are not strictly clean or poorly cleaned. Masturbators should not be borrowed from each other by friends, which can avoid the occurrence of foreskin glansitis, urethritis, and even STDs. With regard to the way to masturbate, what suits you is the best, making full use of your hands is already perfectly adequate for your needs. It is strongly discouraged to use some ways that may bring genital damage, for example, inserting the ding into a bottle of pure water; inserting a pencil into the urethra and other self-inflicted ways of masturbation.
