question: I am a 72 year old male. I am active. As I was walking this afternoon I felt something uncomfortable in my groin area,. When I returned home, I looked in this area and see a bright red area about 2 or 3 inches long. It is sore to the touch. It has an odor. I put zink oxide on it and plan on cleaning the area well when I shower tonight. I do not wear boxer shorts.
