i can vaguely understand this, and the reason is pretty gross so i’ll give you a warning in advance. you don’t see stuff down there and it’s surprisingly easy to miss things if you’ve even gone to the bathroom once after showering... i started taking some some rather obscene photos of myself for reasons and uh, that’s how i realized that i very often had bits of TP down there because that just happens when you use TP. it’s pretty impossible to avoid unless you’re using wet wipes or something every time you use the bathroom, or maybe at least have some very solid TP. i already wipe my ass with water because i’m paranoid but i could easily extrapolate that to poop, without a bidet there will very often be shit remnants in ur ass
