Here are some pictures from before the appointment, with explanations in anatomically correct terminology.
In the above photo is visible the scar tissue formation I mentioned earlier, the "skin bridge." It originates at the circumcision scar to the corona of my glans over the sulcus, and is very tight and painful when my penis becomes erect.
There is a darker blemish on the left side of my penis just distal to the circumcision scar. That small dark dot is a scar from when another "skin bridge" ripped apart from about 1/2 the way up my glans, and bled and hurt badly. This happened when I was 8. I never told anyone about that until now. The blemish on the glans is barely visible on the left side.
There are non-bridging adhesions in the center of my sulcus--two small, cosmetic blemishes where the skin adhered confluent to the sulcus as sequelae to my circumcision. These are sensitive to the touch and get sore very easily.
Like its name implies, things may pass under this unusual bridge. I have awoken to the skin bridge becoming pulled so tightly that it cracks and bleeds, before.
Visible here is a chunk missing from the inner mucosa under the corona of the glans, just to the left of the penile frenulum. Also present are unusual raised, painless, pink bumps on either side of the frenulum. They are likely hirsuties coronae glandis, aka "pearly penile papules," a harmless anatomical variation in penile appearance and form.
Visible on the underside of the shaft is the skin-tag I have on the left side (right on the photo) from a sloppy cut, and just caudal (below) the frenulum there is a darkish dot-like blemish. I think this may have been where they might have injected local anesthetic for when they performed the circumcision, 21 years ago. A similar dark mark is visible on the (formerly) inner mucosa to the right of the frenulum caudal to the sulcus. I have no idea as to what the cause might be for that one.
