A couple months ago I had a benign growth removes from my penile shaft. The other day I noticed what looked like it might be a sore on the scar tissue. Its is dry and not wet at all and it doesn't itch. It looks like after a pimple gets popped, almost like a little crater in the skin. The only sex I have had has been with a condom on, intercourse once a couple months ago and oral with a condom a few times. Does this sound like it could be any std you guys know of? I just have no idea what it could be.
