Hi , i am 27 yrs/ M about 20 days ago I had rough masturbation without lube , and after some time about after 8 hrs my penis starts aching and turns red . There was pain while urination and irritation also . After 3 days pain in urination and pain in penis goes away . Now there is no pain or irritation most of time , glan penis irritates only when i wear tight jeans and walks . may be due to rubbing . But now there are several red rashes on my glan penis . on tip of penis there is quite big rash and my glan penis skin becomes little scaly where the rashes are . Please tell me what to do .
