Does anyone know why the glans of my penis turned a vivid red on one side after two days in my Steelheart? My balls are snug, turning purple briefly before returning to normal. They go purple again whenever I get erections. I suspect it might be too tight, restricting blood flow somewhat. The red area isn’t painful or sore at all. On the opposite side of the glans, there were a couple of tiny red spots. Thanks for any thoughts.
