A little over two weeks ago I noticed some very slight discoloration and swelling around the edges of the head of my penis. It looked as if it were possibly an abrasion from aggressive sexual contact. It was accompanied by minor, occasional itching around my groin - nothing that ever broke into a full rash - maybe once a day I'd get a sense of itchiness on my lower abdomen or beneath my testicles or on my inner thigh and if I scratched it would excite the itching for a little while.
Seeing that no sores seemed to be forming - I reasoned that it was not genital herpes and I applied Lotromin believing it to be a minor case of balanitis or some other fungal rash.
The slight redness and swelling around the head of my penis subsided quickly, whether due to the lotion or not I am unsure. I checked my genitals obsessively for any signs of change over the next couple of weeks, finding that minor itchiness, redness would change locations - sometimes on the underside of my penis, some days on my inner thighs, etc - but other than this noticed no signs of sores or lesions and overall the itchiness, rash, seemed to be subsiding.
Then - two days ago, I noticed a single, almost perfectly round bump on the underside of my penis. It is very small - smaller than an asterix on a computer keyboard. I’m not great with measurements, but possibly 2-3 millimeters in diameter. It is flesh colored and has a dimple or crater in the middle.
The bump is not at all painful. It has been very minorly itchy on just a couple of occasions, but that has subsided.
At first I believed it to be a molloscum contagiosum due to it’s perfect roundness, color, and dimple in the center, and because it didn’t seem to demonstrate the qualities of a herpes sore: it’s a single sore, there’s no blistering/ulceration/redness/breaking of the skin, and there’s no pain or any significant itchiness.
Now, however, after two days I believe the bump appears to be healing - which has me concerned as I’ve read that molloscum take several months to heal. Now I’m concerned that this is a single, healing herpes sore and that I somehow missed the papule and blistering stages...
