to orsocuir :It really depends on the Urologist. I have a kidney stone issue and have been numbed first then watched as he ran a cystoscope into my bladder. It was almost painless. I saw the stones sitting in my bladder.
this is fascinating to see inside the dick and bladder, the shape of the veins, I was scared but these were just air bubbles.
Did you fill your bladder with saline solution or sterile water?
How big is your endoscope? I don't want to end up with an extra large urethra but I'd try it in any of my orifices, even stomach.
