I mean, a stand to pee (STP) device is a thing. They even market them for cis women. They’re pretty common among trans men, but I’ve never used them because I’m squeamish about stuff with piss on it, and also don’t want to miss and piss myself in public.
Some look really unrealistic (basically an angled spout on a cup), some look moderately realistic (the spout is flesh colored and penis sized/shaped), and some are made out of silicone, highly sculpted, realistically colored, and you’d never know it wasn’t a penis.
If someone’s kid is even able to notice the fine details of someone’s genitals or how they’re pissing at a urinal, it’s time to have a talk about where to keep your eyes when you’re in the bathroom, anyway ¯\_(ツ)_/¯
I’ve read that smell fatigue is part of the reason for that, although I’m sure associating it with work doesn’t help! When I find food unappetizing after cooking it I try to step outside for around 5 minutes just to reset my nose. Not long enough for it to get cold. When I go back in it usually is much more appetizing.
