Hey again...
Dino - it is a thrombosed vein that i have (confirmed by a doc). It ran from just under my head as i say all the way into my body on one side of my penis. It was never there before and then came up after i did some really stupid exercises too soon. It is going slowly - it is reduced to about an inch long and softer than it was - but its still there.
My thrombosis is now just before and after the joint where one vein becomes two, all three of which are hard. The vein is not so close to the surface that i can see it - except when i am erect. I think this sounds very similar to yours Priapos. Sorry to be the bearer of bad tidings but in my opinion it sounds like you have a thrombosis.
Your veins should not, repeat not, be hard. This is a sign of a problem as i see it. Lexx - i am also very vascular and can see most of the veins in my arms, feet etc - but if i play with these veins i can feel them but they are soft and pliable. If you have a vein which feels like a piece of string has been inserted under your skin then ther’s a good chance that this is a thrombosis.
Also it can hurt but doesn’t necessarily.
nb to start with my thrombosis was quite short (about the size it is now - but i tried to get back to it too soon after that disappeared - about 3 days - and this made it much worse)
Priapos - if you have to take an extended break, keep in touch - i know what its like. I’ve been climbing the walls.
The only way to know for sure is to go to the doc and drop your pants - wow isn’t that fun.
