I've used many a bidet, and I had one installed before eventually removing it.
Isn't it kind of gross to have shit-spackled water being sprayed around a larger area of your undercarriage? I enjoy a nice bidet, but it just kind of seemed gross to me. You wipe clean, then whatever fecal matter and microbes are left then get sprayed onto your taint? That doesn't really help things much.
Do what I do: only poop in nearby businesses so you never pollute your toilet, and then immediately come home and take a shower.
The nozzle needs to be constantly sanitized, or you're basically just letting shitty water be sprayed on you. Studies have shown that regular use of a bidet disrupts healthy vaginal microflora.
Pregnant women should especially not use a bidet.
Even a constantly (every use) sanitized bidet is generally less sanitary than proper wiping. Using a spray of water to handle fecal material is very obviously suboptimal. I feel like it's absurd that people need to be told this. You might "feel" cleaner, but you just allowed bacteria a vehicle to spread over a larger area of your body.
