hey, I had a question if I had a condition under my penis or not that is std related? I am 150 lbs, 18 years of age, and a couple of weeks ago a random white head came up. the other day I popped it and some blood came out of it, but the next morning the bump looked like it was still there so i squeezed it and not even a fourth a drop of pus or something came out and it hurt if I touched the bump. I have never had any urinery problems, just a minor jock itch it seems like. my shaft skin is not dry or anything, its just located on the left side of my under penis shaft, do you have any idea what this may be? I have only received oral and thats it. the top fourth of the bump had a tiny scab looking thing and itd kind of hurt to touch it
