If you have inflammation after intercourse, a vaginal bacterial culture plus a drug sensitivity test is recommended. Depending on the pathogenic bacteria detected and the sensitivity of the medication, the corresponding medication will be given to achieve a complete cure. If the partner is circumcised, it is recommended to have circumcision or to turn up the foreskin before each intercourse to clean the foreskin to prevent it from entering the vagina and causing local bacterial reproduction, which may lead to vaginal inflammation. In terms of diet, try not to eat spicy and irritating food, and it is recommended to eat more fresh fruits and vegetables to strengthen your body.
