Cock rings and bum veins
This isn’t a terribly exciting injury, but one I haven’t heard of before.
First, I should point out that I get a small, semi-firm bump close to the base near the dorsal vein whenever I constrict my dick below it. I figure it is a wacky spot in a vein (not the dorsal vein itself) that tends to bulge into a ball shape under pressure.
I’ve used wraps and cock rings before, but not for more than a few hours at a time. Several days ago I put a wide rubber band around the whole package. Circulation was good, and I didn’t notice much extra engorgement unless I intentionally got a little fluffed. I’d done this many times without ill effect, except for extra fluid build-up if used immediately after an intense PE session. Well, I fell asleep with it on, so it was on for a total of 12 hours or so. When I took it off that bump in my vein was the size of a BB and hard as a rock. And it stayed that way. Shit!
I did a light pumping session, and within 2 days or so the bump shrank and softened almost back to usual. I can still feel it with my hands occasionally when I jelq over it hard.
The purpose for posting this is to warn anyone with a problematic vein to avoid using cock rings for long durations, or at least work up slowly and monitor what is going on. I think anyone with a thrombosed vein should stay away from them entirely.
