Sometimes when I'm jacking off a vein on the side of my penis kinda puffs up. Is it cuz I'm doin it till I cum then I stop so I could do it longer? If I'm confusing tell me.
It could just be that when you are aroused, blood pumps faster through your body, and since a lot of it is held in your penis to cause the erection it gets a bit blocked up.

I wanna be noticed...
I never really noticed if it was a vein. I just assumed it was. I'll get back to you about that later tonight lol.
To achieve erection the artery into the penis is widened, and the main vein out is pinched off. The result is the blood pressure inside increases, but there is no flow of blood. That may be causing some ballooning in a weaker part of a vein, perhaps at a valve.
Well, I have a big vein too. It pumps up not when I 'm hard, but when I 'm limp and excited (just before getting hard). Therefore, I guess it's quite normal (unless you see something weird, like blood, or color change).
