Hi I am 39, and circumcised. I have this strange thing under my skin. It is just below the head of the penis where the second part of the penis body started. It just look like a swalloned thick vein with bumpy in few places. Looks like pus inside the vein and it might explode anytime. But when I touch it, it is hard and don't feel like any liquid inside; but looks like something inside. It's been almost two week now getting worse every time I have sex. I don't feel comfortable to discuss this with my family doctor. If needed I can email you some photos to review. Please advise me something.
