So, I'm stuck away from my pc and 3d printer and with only a sheet of paper for designing. So random ideas season.
Design is based on the assumption pressure goes up the more pee you have in your bladder.
So here's the idea, get one of those urethral chastities with actually good sealing. Connect a tunable pressure regulator. Set the pressure regulator to maximum pressure which will prevent flow and wait for the urge to piss. One the desired urge to piss has been achieved slowly reduce the pressure while trying as hard as you can to squeeze piss out. Once piss starts to flow just turn the pressure regulator up a bit more to achieve the desired control. It is also a good idea to hook up a catheter bag.
If my assumption holds water (pun intended) you should constantly feel the need to piss and if you squeeze hard you let off excess piss yet you still feel the urge. Utterly evil.
