I have been getting red spot/ulcers on the tip of my penis and foreskin for about a year, i have never had unprotected sex and have only had two sexual partners. The spots do not itch, hurt, smell or pop but they do seem to spread and stay present for around a week until fading. However, I have had cold sores since i was 5/6, is it possible that i may have passed the virus by touch from my mouth to penis when i was younger without knowing or is it possible that it could be something other than herpes?
