Hi,
Noted the history about your partner about deep cuts on penis due to penetrative sex, not healing in spite of Sudocrem, Savlon and Bepathen. You both are in committed relationship.
The commonest cause I can think about is as follows:
The skin is thin and can bed cut during penetrative sex due to dry vagina since there is no lubrication.
Balanoposthitis that is inflammation of the glans and foreskin.
Possible diabetes.
You having
vaginitis transfering the STD known to occur even in committed relationship.
Hence I would advise you both the following:
Consult a General Surgeon to see for the exact effect of the problems, rule out diabetes and other diseases which can affect the life.
Yourself to consult a Gynecologist and see for any disease that can be treated well.
If there is long prepuce then he may need a
circumcision.
Till then apply Liquid
Povidone Iodine to the affected area after cleaning with plain water three times a day.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant, ENT & General Surgeon
