Ok i have a big vein that runs from my right base of dick to the head. On the left side of it runs a hard little skinny vein it feel like a guitar string. But i only see it when i do girth exercises it doesn't hurt at all it sort of runs across my big vein and is sort of squiggly and i can sort of move it left and right when its full of blood. I can sort of feel it when iam flaccid but can't see it at all. IT sort of feel like a couple of other veins on my penis also like i said there is no pain at all and its not geting any bigger or anything i dont think is this a problem or just a vein or capillary or something ive been hearing alout about thrombosed veins or something but iam not sure if this is one no pain, only see it when i do girth and am really hard. ANY ADVICE!!! IS this just a normal vein?
