If there is a lot of white discharge after intercourse, it is often clinically caused by the following reasons: 1. There are miscellaneous bacterial infections in the vagina, causing a discharge similar to paste. It is recommended to do routine laboratory tests of the leucorrhoea and give appropriate medication according to the results. 2. caused by Candida albicans infection, the discharge is not only white, but also tofu-like, accompanied by vulvar itching or local redness of the vulva. It is advisable to use clotrimazole suppositories or terbinafine vaginal tablets to be inserted into the vagina for a week until the clinical symptoms disappear. However, it should be noted that pregnancy is not allowed during the treatment period, so it is recommended to take contraceptive measures if you have sexual intercourse after treatment.
