I have a strange situation that has 'persisted' for years now. For at least 5 years now, I've had these bumps on my scrotum that don't seem to go away. From what I can tell, they haven't really increased in number, but I think what is already there has been there for a long time. These bumps were there long before I was ever sexually active in any capacity, so I know it's not an STD or something caused by sexual contact. The bumps themselves are usually fairly hard. Just recently I found an unconventional method of extracting a couple to try and help figure out what they are. The bumps seem to be caused by these tough sacs or 'balls' that are filled with a whitish/yellowish substance. Not liquid, but a soft "cheesy" sort of consistency. Each bump occurrence only has one of these sacs, but there are a fair number of them which causing me to fairly self-conscious. Any ideas? I used to think it might be molluscum contagiosum, however the bumps don't really have the 'indent' in the middle that seems to be classic of molluscum contagiosum, and they've been there for 5 years at least. I've read that molluscum usually clears up in 2 years at most without treatment.
