so it's been at least a year since I first noticed this. I have sort of a ring on my foreskin that is empty in the center, when I am erect this ring turns sort of into a bump and still has the empty center. There is no irritation or pain. I have had no form of any sexual contact with anyone ever so STD's are out of the question. I asked my doctor what it was the last time I had a physical and he said it might just be a harmless wary but I want to know exactly what it is. Here is a links to a photo representing my issue.
