Hi,
As you are HSV2 positive, therefore, you might be having sores or blisters of vagina, which might cause pain during as well as post intercourse period. Also, vigorous thrusts during sex may also cause erosions or other minor injuries of vagina or
cervix etc. during the act of intercourse, which may result in pain during or after intercourse.
Therefore, you are advised to take some anti pain or anti-inflammatory OTC drug to control the pain / inflammation etc. Usually the symptoms should go themselves, with time.
However, if the symptoms do not subside within a short period or become intense in severity, then you are advised to see your doctor and treatment done accordingly, as you may need some antibiotic or anti fungal treatment, if there is some bacterial or
fungal infection etc. is also present.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Satnarain Bansal, General & Family Physician
