For about the last 2 weeks I have noticed a few weird things about my penis and I was wondering what it could be and how it could be treated?

I am uncircumsized and have not have sex in over a year. I haven't messed around with a girl in about 2 months so I really doubt it could be an std.

But about 2 weeks ago I noticed that my penis had a funny, musky smell to it. I just figured it was from sweating hard at work. I went home and washed real good down there and didn't notice it for the rest of the day. Then the next day the same thing happened. The same musky, almost urine type smell has been coming from my penis since then. Sometimes not even washing real good can take it away or only keeps it away from a little bit.

Then two or so days ago I started noticing little black bumps on the head of my penis. There are only about 4-5 of them, right at the top of the head. And where my pee-hole is, it is swollen on the end, it almost looks like lips.

I was wondering what could be wrong with me? And how should I treat this?
