         | Well ... I don't have a bidet but doesn't mean I don't wash my
         | buttocks after doing business. Unfortunately it's a bit of a
         | taboo subject so it's not discussed, not taught in school /
         | hygiene classes, just let it be.
         | 
         | Best example I heard from someone is this: imagine you dip your
         | hands in Nutella. Then try to clean them just wiping with
         | toilet paper, for more authenticity, without looking. Then look
         | at the result, that's your ass, good thing you got underpants!
         | Compare that with washing with soap and water!
         | 
         | So how do I do it?
         | 
         | - First step it to use _wet_ toilet paper. I can 't stand raw
         | toilet paper, it scratches my hemorrhoids, so I pre-soak it in
         | water from the tap if available or just water I keep in my
         | mouth if in a public place / at work. I hate public places for
         | this matter. This way it's much gentler for the tushy, it also
         | pre-washes the area and third advantage, it's much less likely
         | to clog the toilet when I flush, being already soaked.
         | 
         | - So after the first step I'm closer to washing Nutella than
         | wiping it. If in a public place, that's the best I got. If at
         | home, next step is wash my butt with soap and water in a
         | plastic bucket. There, that's your bidet! For 2 bucks, you too
         | can get one! :) Sure, you have to squat and not wear any pants,
         | but you're in your own freaking bathroom. Dry with paper towels
         | which you throw in a bucket. Plus, comes the third step anyway
         | and you won't be wearing any clothes for that.
         | 
         | - Third step is taking a quick shower. At this point you won't
         | be leaving a trail of poo into the shower drain or bath tub (I
         | shower in the bath tub) but still get to clean your general
         | areas that were in contact with the toilet, hence e-coli and
         | sh*t (no pun intended), plus shower feels good.
         | 
         | So there's that: my overly complicated toilet routine that
         | takes some 3 minutes extra after finishing with the toilet
         | proper, which leaves me perfectly adequate for entering a pool.
         | Unfortunately I also know that 99.98% of the population
         | entering said pool has their Nutella butt washed for the first
         | time in said pool, so no pools for me if I can avoid it.

       | In almost all of SE Asia, especially Thailand, Vietnam, Malaysia,
       | all of the toilets come with a hand-held sprayer. They also had
       | this in the Doha airport and I'm not sure how common this style
       | is outside of SE Asia but I'm guessing it's common. Japanese
       | style bidets are very common in Korean households as well and I'm
       | sure its easily a billion dollar business.
       | 
       | It is nice but the functionality is quite difficult for a person
       | who's not used to this whatsoever. After you're done sh*ing, you
       | grab the handheld sprayer and turn it upside down and reach
       | behind you toward your butt and try as best as you can to aim it
       | into your anus to wash as best as you can. People who have been
       | doing this their whole lives can probably aim with a precision of
       | a Marine Corp Sniper but to us, we look at it as alien
       | technology. It's is quite difficult to use for a first timer and
       | there are factors that worry us.
       | 
       | If its not aimed correctly, where does the splash go? If you're
       | lucky it stays in the toilet boil. However if your aim is off,
       | you can completely miss your anus and either shoot to much under
       | or over which will shoot the water outside of the toilet bowl.
       | 
       | Also when I was using the bathroom in the Doha airport, the
       | handheld sprayer had a soap dispenser next to it. I was curious
       | what it was for so I YouTube'd and searched for instructions on
       | what the soap dispenser was for and (kind-of) to my surprise it
       | was soap to lather and clean your anus with your other free hand.
       | After you lather and clean, you basically rinse your hand with
       | the hose as well.

         | Why not from the front? It makes way more sense. Easier to aim
         | and your butt seals against the back edge of bowl hole so the
         | water doesn't splash out.

       | I think paper is perfectly fine for most people who do not have

       | 
       | The main one is diet. Eat enough fiber so it's not a mess in the
       | first place. This has many other benefits too. The next in
       | priority is wet wipes. I strongly prefer them, and they are
       | portable unlike a bidet. They are super useful while away from
       | the toilet as well. After that there's technique. I am confident
       | that the people who complain about paper and wet wipes are simply
       | wiping way too hard causing chafing or even fissures. I don't
       | want to get too graphic, but you also need to "relax" a bit down
       | there for the most thorough job instead of just a surface level
       | wipe. Normal paper first for removal of the "bulk material" and
       | wet wipes for the residue.
       | 
       | That's it folks! If you do all this right, washing your hands
       | afterwards shouldn't need so much effort either.
       | 
       | Bonus tip: why not just carry a little atomizer bottle filled
       | with water so you can make your own wet wipes in a pinch? The
       | spray is gentle enough to not completely saturate and ruin even
       | the thinnest and cheapest toilet paper you find in the wild, and
       | such a spray bottle is again very useful away from the toilet.

       | If anyone wants to explore the bidet space without replacing an

       | bowl, and attach to the toilet's water supply with a tee fitting
       | and one-way valve, either at the wall valve, or at the bottom of
