Think of it like a hose nozzle. Only the sharp stream setting is going to be really good for standing up. Most guys have jet, but that does get quite a lot of splatter and just isn’t as clean. Now think about us girls set on shower, mist, fan, soaker, cone, angle – it’s really just so much easier to sit down.
@MissAnthrope I have a friend who has one of those for when she goes to Coachella. She’s got some thing where she’s afraid to squat for a piss but not to take a dump. So much maintenance.
