Ugh, I rarely hover over a toilet bowl. More trouble than it's worth. If some asshole left pee on the seat before me, I wipe it up with TP, put some antibacterial sanitizer on some TP and wipe again, then sit down and go.
The one exception was at a bathroom in the NYC subway...that was seriously the dirtiest bathroom I had ever seen. Smelled like piss, had random underwear on the floor...but I really needed to go. I hovered, wiped myself with a napkin out of my purse, used another napkin to flush the toilet. Used hand sanitizer on hands.
That entire day was probably the longest I had held it in continuously because up in NYC, there just aren't many public restrooms. That entire day was...hold as long as possible, oh thank God a McDonalds, hold as long as possible, oh good our lunch spot has a toilet, hold as long as possible, omg diarrhea from the restaurant is setting in, please lord let there be a bathroom somewhere, oh good there's one in brooklyn bridge park, oh crap its on the other side, no don't crap you can't you don't own any other pants, finally thank god I can go for the next forever. Satisfied for now. Hold as long as possible, oh look there's one in the subway station at our stop, dear god no this is disgusting but I must go...hover and run.
