I have a smallish red spot on the right top edge of my penis head, as well as a blotchy red area on the dorsal side of the shaft, in the top area where I was circumcised. The spots/blotches are painless, do not itchy, and might be very slightly raised, but not very noticeably so. I currently am in a committed relationship and we do not use condoms, but neither of us have ever experienced any problems or concerns regarding STDs. I assume it is some kind of friction irritation, but am concerned it is something more serious.
