Vaginitis is not allowed to have intercourse. Vaginitis, especially trichomoniasis, can be transmitted through sex, so sex is absolutely forbidden during the treatment of trichomoniasis. In addition, some patients with mycotic vaginitis can also be infected through sexual contact, so it is also important for patients with mycotic vaginitis to refrain from having sex. For bacterial vaginitis, sex is also generally prohibited during the treatment period, otherwise it will affect the effectiveness of the treatment. For senile atrophic vaginitis, sex is also prohibited during the treatment period because of vaginal inflammation and if intercourse at this time is likely to cause discomfort in the same room. In general, regardless of the type of vaginitis, it is recommended to have sex after the vaginitis is cured.
