Just thought I'd post this. After a rep of dual compression squeezes while clamping today I noticed that my right hand had a bit of blood on it and my head had a fair amount on it as well. It seemed to be coming from the urethra, now the bleeding did not continue and it seems as though it might have been a small skin tear right at the top of the urethral opening. I'm fairly sure that I'm ok, but I do think that I over did the internal pressure a bit while performing this particular exercise. Tomorrow and Tuesday are planned days off, but this was a bit of an eye opener for me. Has anyone else had something similar happen to them?
