Hi, The Skin On The Left Underside Of My Penis,

Hi,

The skin on the left underside of my penis, at the base is red, irritated, and looks as if there may be small tears that only hurt when I become sexually aroused and/or active. Every time I become erect, the area becomes more inflamed and painful. I tried using lotion as a moisturizer for a few days, however this did not help. What do you think this is and how should I treat it?

Thank you
