question: Hello doctor, I am a 60-year-old male and I am not sexually active. After masturbation, I use a moisturizing lotion. I developed a sore on the shaft of my penis. It is not painful and does not itch, but there is a slight awareness of sensation. This could be due to the bump catching friction as opposed to the smoother areas. In my lifetime, I had an occasional clogged pore or pimple when I was a virgin. I had examinations and never been diagnosed with an STD or genital warts.
