Typo in the original comment. Side of mark is 1/8" not 1.8"
Thanks for the reply. Why do you doubt it is STD related? Is there some other symptom(s) I should be experiencing for it to be more likely to be an STD?
I recommend a full STD check after an oral exposure. I'm in the same trouble.
We do not diagnosis on this website.
Skin issues are too complex to even have an indication what this might be, best idea is to see a Dr for an exam. Doubt this is STD related.
Is there any way to post a pic of the affected area too to help with the diagnosis?
