are you circumcised?
in our read before posting post we explain why no photos are allowed.

no I'm not circumcised. the bump goes along, not around the shaft.
well it's not likely this is a std since it's been there this long. It actually sounds normal to be honest. if you are concerned, be seen and get a proper exam to get better answers.
I also noticed a small detail. the bump has a little hole in it and when squeezed produces a very little amout of liquid, but the bump remains firm. could it be sweat gland infammation or something?
