You can have sex if you have no symptoms of vaginitis and your tests are normal. When a woman is examined for vaginitis, she needs to avoid sexual intercourse during treatment to prevent cross-infection. If the symptoms disappear after treatment and the vaginal secretions are rechecked after stopping the medication and the test results are normal, you can start having sex. When having sex, pay attention to the hygiene of both parties to avoid reoccurrence of infection. In the following life, pay attention to daily care to prevent the recurrence of vaginitis. Don’t wash the vagina excessively, so as not to cause the internal environment of the vagina to be disorganized. Choose breathable underwear, and be diligent in changing and washing. Don’t sit for a long time, and keep the vulva clean and dry.
