We talking bidets??
Seen this one joint in Tokyo that had an electronic menu with an assortment of options to choose from. You can choose from male/female options, with each having different pressure, and location where the water is squirted (number one or two).

Thing had a heated seat, and you toggle through the levels of warmth
Whole thing was in Japanese so I'm pressing random buttons on that thing and my face cycling through

and then

when you hit the right level for the heated seats and the ass washer.
Oh, and that thing had an electronic seat cover lifter that's synced with the door opening
That's a life goal having one of those joints in my home.
