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 from drinking water. More than a full liter of water went inside through the tube and expanded my walls. 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, forcing 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!
