Second, vulvovaginal pseudomonal yeast disease can cause not only vulvar itching, but also vulvar redness and swelling and tofu-like vaginal discharge. Third, trichomonas vaginalis causes vulvar itching and frothy discharge, and this inflammation is transmitted through sexual contact. Fourth, mycoplasma vaginitis causes itching of the vulva and is accompanied by frequent and urgent urination.
