I'm thinking I may have one. It seems to resemble one. I have what feels like a sort of a "lump" that starts near the base of my penis on top and left of the center as I look down on it. Feels like it is approximately 2" long and has a few small (maybe 1/8") bumps on it. It does not hurt and while it resembles thrombosed viens that I have had in the past...I am puzzled because I have not done any girth work and have only gotten thrombosed viens from girth work, not stretching . Other notes, it is maybe 1/8" wide, is smooth for about the first 1/4" then, has a small bump, some smooth area for a little more, then another bump, smooth again ...about 4 total of these small bumps pretty close to each other then, the rest of it is smooth. I'm not really worried about it and am not going to stop stretching because of it. Theres no pain and I know it's not anything serious. I was just wondering if anyone else has seen anything like this after a lot of intense manual stretching . I've done a lot of hanging in the past and never had this before. I thought maybe I could have irritated a ligament or other similar fiber/tissue and maybe it is not a vien at all??
