its about pimple size maybe a little larger
I haven't a clue really but i have the same thing you're talking about. I should really go to the doctor and ask, but its never really been an issue.
If you find out before i do let me know man. I seem to remember nicking myself around there and then this showing up.
It sounds like it might be a small thrombosis, which is a swelling/clot in the vein, since it gets bigger when you get an erection. Or it could be an infected pore or something. However - and I don't think that this is what you have! - painless, very hard nodules can sometimes be cancer. Best to get this looked at ASAP. I bet it's nothing, but you don't want to take any chances.
Well, my bump got irritated yesterday and turned almost like a pimple does when its about to explode. Mind you it looked like normal skin just raised prior to all of this. So i got pissed and i popped it and a puss similar to that of a popped pimple came out.i cleaned it up but it was still really irritated. I sterilized a pin and was picking the scab off when i was able to actually pull out the hard substance below. It hurt a bit but it was like a tiny hard dried ball of white oil (same kind as a pimple).i pushed all of it out and cleaned it up and the bump is completely gone. I had this for well over 2 years before it reached this stage. Crazy
I have the same thing to but mine is raised but still under skin and is a little black. Also mine is on the upper shaft/foreskin. If anyone knows what this is tell me!
I have had mine about 7 years also!!!!!!!!
