You should not have intercourse when you have mycosis vaginalis to avoid aggravating the symptoms of vaginitis and cross-infection. Mycosis vaginalis is a common gynecological vaginal inflammation, mainly endogenous infection. Pseudomycetes are parasitic in the body and can cause infections when conditions are suitable, as well as through intercourse and indirect transmission. Mycosis vaginalis is characterized by a marked increase in milky or pea-like discharge, itching and burning, frequent and painful urination, painful intercourse, and edema and congestion of the vulva and vagina. In the treatment, antifungal drugs can be used systemically or locally. Sexual partners with symptoms should be treated actively to avoid repeated infections. You should pay attention to vulvar hygiene, keep your vulva clean and dry, and change your underwear regularly. The intimate clothing used should be disinfected and scalded with boiling water. Keep warm, avoid getting cold, and exercise to improve your immune system to prevent mycotic vaginitis.
