NSFW What are considered normal bumps on the shaft of the penis?

I have encountered little dots (about 5) of them near the bottom of the shaft of the penis. I have been steady with the same female for over a year. I have not cheated or anything like that. The bumps kind of have a little puss at the end, like a zit, but not red or sore on the edges. Well I’ve had them for about 4 months now easily, I’d say. Two days ago I popped the juices (puss/yellow) out of it. I thought, perhaps in growns? And then today as I showered I noticed a swelling in that area. About 3 centimeters in diameter. I popped the puss out again. I just checked again and I noticed the other bumps don’t really have a yellow puss thingy. Any help? Photo links would help!
