Thrombosed vein or another "rib" on my dick
Well I clamped for over 10 minutes today for 15 and not really even that tight (I have been consistently PEing for over 4 months). Well i was masturbating during the whole session which I believe adds more pressure, but also gives me something to do, and you can practice your edging. Well when I removed the clamp a vein on the right side of my dick was hugely pushed out and looked pretty weird (maybe around 1/4 a marble) however I massaged it (was not hard at all) and maybe 2 minutes after I took the clamp off it was not too noticeable.
4 hours later it is red and a little puffed up, but not hard or painful at all. It actually looks a lot like another vein that is an inch or two under this new one. I believe they were called ribs by drilla and a few others, and they look identical. No pain so I guess i may take a couple days off and get back into it and see how it feels, (no pain when i jelq) but i will stop if it starts to hurt. To everyone out there, just be careful if clamping for over 10 minutes.
