Still something to see a Dr about, does not sound STD related.
Ok. forgot to mention, i also have muscle twitching on my testicles.
i don't know how to explain, but it similar to after you have overworkout on your hands and its muscle started shaking by itself.
is there a sympton i should be concern about?
See a Dr. Bumps and things like that can be many things often not a STD, but only a Dr can tell you what it is.
