I have had problems with folliculitis in my recent history and I regularly shave my penis as well as pubic are and scrotum. Recently I noticed a small bum on the shaft of my penis. Needless to say I got scared of herpes immediately. It's not red, nor is it a sore. It's not open or bleeding. It's skin colored with a white dot in the middle. It's very tender am to the touch doesn't hurt but when applied pressure leaves a residual stinging. As I stated I do shave my shaft but have never experienced this before. Can someone please enlighten me as to what this "might" be?
