Sir before 4 months my morning erection goes out. But it some time come like 40% of time and (I am not done sex yet) After 15 days some infection in my urine. I feel some uncomfortable in penis. Urologist give me antibiotique for 1 month but no relief. So I decide done Cystoscopy and found infection and urethral structure. Doctor give antibiotics and cauterization for 5 days. And give again antibiotics for 1 month. But after this I found my morning erection totally goes out (25 days go). I feel some irritation in penis till now. I done all test in hospitalisation all are OK. But why my morning erection not come? Why I did not relief from infection after taking long term medicine (levofloxacin)?
