And let me stress out once again urinal (condom), if you are leaking, just put it on and you are done.
The engineer in me has thought about this problem.
As an alternative to suction for PureWick and PrimaFit could be a capacitive moisture detection probe that could operate a pump that does not suck too hard. The problem is where it comes out while seated is lower than higher parts of the tube so a pump is required. The pump will need to match peak flow.
