You might be suffering from a genital infection that has affected your penis. This infection's symptoms could be redness, itchiness, strange discharge, or a hurt while you urinate. Infections can be caused by bacteria, viruses, or fungi. The first thing you need to do is wash and dry the genital area. You should not have sex until the infection is gone. You may do better with the homeowner antifungal or antibacterial cream you may buy, but if the symptoms are still there, you better go to a urologist.
