Can I fit the minicam AND a catheter inside my pee hole at the same time? YES I can! And this is how it went! The catheter allowed me to inflate and deflate my bladder as I liked while the cam was looking inside all the time. My Bladder went fom being empty wrinkly to fully stretched out to its limit within just a few minutes. That's a 100-times faster inflation than you could get naturally. More than a full liter of water went inside through the tube and epnded my walls with its pressure.I held it in for a bit to get a good look before starting to release it again. I could feel my blader contracting uncontrollably, pushing out the water and forming shiny creases again. When it was all emptied out it was just a few centimeters in size. It's incredible how it can grow to a multiple of its size and then shrink again so fast. And it feels so nice too!
