Small amount of blood came out of urethra.

Hello all, as the title says, for the first time in nearly 10 years of PE, the smallest amount of blood came out of my urethra. For the past few months I have been doing a Manuel girth routine, its been working great, but it is very intense. While doing the 4th set of movements during my routine, which are those, reverse head jelgs, The one where you do a uli squeeze, and squeeze tightly around the head, and go down the head, then hold it(I forget the name for it).

While doing the 4th rep, I squeezed way to hard on my head! And I felt something shoot into my hand, I thought I had accidentally ejaculated, but when I looked, it was a extremely small amount of blood, mixed with some pre ejaculate(and I mean almost microscopic). I felt no pain, and I am in no pain now, and there is no more blood coming out. Two weeks ago, when I finished my routine, I noticed a small amount of dried blood near my urethra, I only saw it by a flook chance, but I ruled it out, as dry blood from my fingers, because I had a nose bleed not to long before, but looking back, I think it was also from squeezing to hard..

I went on to edge a little more, and careful jelqs to see if any pain or blood started coming out, nothing happened, so I lightly finished my routine, cutting a little short for safety. I urinated not long after, no blood or pain(thank god). It is defiantly something within the head region, because there was pain no where else, and if it was from deeper within, more blood would of came out when I urinated.

When doing that exercise, DO NOT!! Squeeze your head to hard I was literally doing a kung fu death grip. I mean it is one of the most intense manual girth exercises.
