3 and half months ago I recieved a partially protected oral sex from a csw(transsexual). The clndom covered 60% of my penis. The past 4 days I've noticed a black patch(open sore or ulcer. I don't know how to call it). This black patch is in the exact position as of a fordyce spot which I was scratching with my nails. Not vigorous scratching. I noticed the fordyce spot 10 days earlier and I don't know if it was a blister.
I doubt it to be a blister because it was so tiny and resembled all the other fordyce spots. And it had changed into the black patch mentioned above only 7-10 days later.
The black patch however does not itch, burn or do anything even when I press or poke it.

1. Can blisters be as tiny as a fordyce spot?
2. Does this black patch resemble anything like a herpes lesion in any of the stages of an outbreak?
I am worried because this has appeared at the exact location when I did not have the condom covered.
