I don't know about you, but whenever I use a public restroom, I remove my pants entirely and do a sort of sideways Captain Morgain over the toilet. If I go down too low, of course, my junk touches the bowl.
I haven’t shit outside of my house since covid so I am very rusty, but yeah, I cross the little gap and then lay two strips up and down either side. I’ve used those prebuilt seat protectors too but they’re never there when I’ve gone in the past
However, more importantly, you can drape TP over the auto flush sensor to make sure it doesn’t spray saltwater on your balls every time you move.
If it's inside the wall, spit on the tp, then stick it to the wall so it hangs down over the sensor. Be sure to wipe your spit off the wall when you're done, ya pig.
