I didn't know whether to post this in the Urology forum or Dermatology forum, feel free to move it if it belongs elsewhere.
About 42 days ago, I had a protected sexual encounter with a stripper. I am prefacing my question with that because prior to that experience I never really looked at my penis as closely as I have since, so I can't comment on how long I have had these. Recently I noticed 3 dark black dots on my penis foreskin. They are flat, circular, and painless. If I had to describe it, I'd say it looks like someone touched my penis with a black marker. Not very big but dark and noticeable. I had my PCP look at my penis last week and when he noticed the black dot he said "have you seen this before?". I said "I haven't really paid attention to my penis since recently, is that dot a cause for concern?", and he said he didn't think so. Then again, when I told him I had fordyce spots on my lips, he didn't know what fordyce spots were, so I'm guessing he is not knowledgeable on skin conditions.
Just wondering, what are painless flat black spots on the penis? One is located in the middle left of my penis, and the other two are a few cm's below the tip of my foreskin. Obviously, since i mentioned 42 days since an encounter with a stripper, my main fear is whether this is STD/herpes/HIV related. I hope someone could shed light on this. Again, if this question is better suited for another section, please let me know and I can repost it there.
Also, would a dermatologist or urologist be better to look at this, if I decide to pursue a medical opinion?
Thanks so much.
