Vaginitis is related to sexual intercourse. Some men are circumcised and have a lot of bacteria in their vagina during sex, which can lead to vaginal inflammation. If you do not pay attention to hygiene before and after intercourse, such as not washing, the vagina is in a humid environment, which can cause bacteria to multiply, resulting in abnormal leucorrhea, itching, odor, redness and swelling. This can cause abnormal leucorrhea, itching, odor, and redness. It is important to pay attention to personal hygiene as much as possible, such as washing before and after sex, to avoid this situation. However, sex is not the only factor that can cause vaginal inflammation, but it can also cause vaginal inflammation if you are weak, have a weakened resistance, and do not take care of your hygiene.
