Bidet / washlet. Your life will forever be divided into a time before you had one, and a time after you had one. You may no longer enjoy vacations because of the lack of one.
I cant fucking stand water flossers, the feeling is much worse than regular floss, it kind of tickles in a really annoying way. Besides dentists seem to prefer people use regular floss anyway.
I mean, literally anyone who's used a bidet before will know from daily experience that your comments are just wrong. It's not difficult to dry off, in fact it's pretty simple, and it uses much less toilet paper than the old way. The primary purpose of a bidet for most people also isn't TP conservation - that's just one of several nice side-effects.
I'm gonna duck out of any further replies here though because, frankly, you seem more interested in pushing this weird narrative you've settled on (in an old / dead thread, no less) than actually discussing it, and I can think of about a hundred things I'd rather be doing with my time. You do you, clean your butt whichever way makes the most sense to you.
