New brown spot on glans

A few months ago I was with someone and a few days later I noticed a very small dark brown spot and a bigger brown spot on the glans. It’s right on the edge of the glans and it’s been there for months now. It hasn’t gone away or changed at all. It’s completely flat and when I get an erection it becomes a little less visible. Has anyone ever had this problem? I’m worried it could be some sort of STD since it appeared after being with that person. Any help would be amazing

Have you ever had any problem like this before.  Could be little blood spots from sex or could be a mole.  if your worried play it safe and see a doctor  ken 

Is there a way you can post a picture? I know you can if you are on a computer you can or message me . I'm a urologist in training so I may be able to help

No I’ve never had a problem like this before. I’ve seen a doctor , I had a full std panel but only 10 days after exposure. I had a second hiv 4th generation test at a month which was negative. The doctor said the spot was nothing to worry about but didn’t tell me what it could Be. The main reason I’m concerned is because it appeared after that sexual encounter. 

I’m unable to post a picture. The spot is completely flat. If I were to close my eyes and feel over I would not be able to notice a difference in texture. When I stretch the skin out of the larger spot it kind of fades away but the smaller spot stays and looks more like a mole. 

If it becomes less visible when you stretch it out I doubt it's an std. Stds infect the top layer the bottom layer if they can but if it were an std it would infect further and not just the top layer of dermis. Essentially, whatever it is it's only on the top layer and stds don't just do top layers. If it becomes less visible when stretches that means the pigments aren't very close but close enough for you to see it. I would think it's just a simple pigmentation

.Probably a case of

  False Cause:  the fallacy committed when an argument mistakenly attempts to establish a causal connection.

Post hoc ergo propter hoc:  (literally "after this, therefore because of this&quot the fallacy of arguing that one event was caused by another event merely because it occurred after that event.

Can you take a look at my issue?

Mine appears to be going away slowly. Any ideas what this could be?

I treated it like ringworm but didn't work.
