It seems that you may be having candidal balanoposthitis
. It is a fungal infection
caused by Candida albicans. You shoulbe investigated for DM,HIV and other immunocompromised conditions. I prescribe in cases like you, antifungal like itroconazole or ketoconazole
for two weeks. I also suggest to apply clotrimazole
cream. Wsh the area with water containing dettol. I hope you got my answer.
