I expect the girls will have better control than guys as the device will not unexpectedly put out a spray pattern or shoot left or right from where you aim it.

A penis is at times a contrary piece of weaponry girls and does take some skill to shoot straight right at the start.

I got 40 out of 60 on that test but I have managed to pee successfully for 51 years and believe that the last 2 conclusions are erroneous. It is in fact a matter of personal choice rather than laid down etiquette.
