Okay, I just tried to this and it failed. Some of it ran down my leg, which was gross.
the other problem I have with this even if it had worked, since my pelvic basically has to be directly above the toilet, that means my pants which are pulled down some are going to be touching/pressing against the toilet bowl outside. Now some public restrooms are icky and I don't want my clothes touching the outside of the toilet, which sometimes has dried urine on it.
I'd rather use a STP device and stand back. that way nothing splashes on me too. and my pants won't touch.
I know I'm a germphob. but I thought I'd post this for anyone else who doesn't like pee on them.
