question: Hello doctor,I am a 29-year-old male. I am having redness on the penis head and urge to urinate for the past four months. I had a habit of masturbation, but now I have stopped it. Can it be due to any structural defect in the penis due to masturbation? I took five days course of antibiotics and T-bact ointment, but there is no use. I have done urine culture, KUB test, UFM test and blood sugar test. All results are normal. Please help.
