I scoot forward or slide back to get a finger down there if needed, usually scooting back and going in from the side of the package. If my business is done i can slide back far enough that my butthole is over the seat and spread pretty wide. When standing i got my pants and underwear in the way and gotta bend the knees and spread the thighs a bit to get a good angle while trying to aim that last squirt.
Sitting also gives better access to push on the part between the balls and butthole which can reduce post piss drippage.
I feel like standing helps with that more because you aren’t confined by the size of the bowl.
