Hello, what can I do to reduce swelling in my vaginal lips after sex?

It is normal for the vaginal lips to swell after sexual intercourse, and it usually resolves on its own after some time. You can try taking warm-cold baths or applying cold compresses if you'd like. If you experience other symptoms such as itching, discomfort, burning during urination, abnormal or colored discharge, it could indicate an infection. If you are concerned about your symptoms, it's best to consult a healthcare professional for further evaluation and treatment.
