....if you need to shit immediately after doing the deed, would that mean the shit was there all along and your boyfriend just plugged a shithole full of shit ready to come out? It seems the prophecy holds true https://www.mangago.zone/thing/about/823549/

Thata really not the point.
First of all, it really isnt the seme's responsability to bathe the uke. But if its his house, then yea i expect him to bring something (often a little towel or toilet paper) so that i can clean up a bit and then i go shower.
But if you are saying that in your experience (or from people you know), its common practice for the girl (or bottom) to fall asleep right after sex and the man proceeds to bath you. Then im honestly quite surprised.

Im referring to the bathing part( ̄∇ ̄").
Don't take this the wrong way, this is just how I speak normally with no intention of mean/rude manner of speech. (Ah looks like I typed way to long)
It's only you doesn't mean all the other does the same as you. (((;ꏿ_ꏿ;)))
Wiping/bathing them OR together after doing it is a way to shows their deep care for their partner because the bottom will ofc be tired and they want to tend them so that they can relax.(It's not cultural it's a deep sign of effection of love and care that they are willing to go through evn to the point of helping in bathing/wiping the sweat because like I've said bottoming ain't easy. Also I'm not saying that if your partner doesn't do this doesn't mean why have less effection NO that's not what I mean, im just talking in a sense for those who clean up after their partner. ) ヾ(*’O’*)/
(Ps: im a virgin and I chose to be one it's all from my friends who have experience:)
And if you don't do this doesn't mean the other couples dont do the same. You have no say on what shud be done and what should be not just because you don't do it. (That's y I said this sounds dumb).ヽ༼⁰o⁰;༽ノ
It's like you're trying to say "Most of us human eat food with a frock, spoon and a knife so the other should do it this way because that's how it's done." (Even I you don't mean it this way, this is just how it sounds like)
Because food can be eaten with bare hands after washing them. (This is what we're trying to say to you).
And don't get me wrong but most part of the reasons why the stories goes on with this plot is to show the readers that the TOP have a deep effection to the BOT. Cleaning after the bottom after sex shows that the Top knows how much energy draining it is for the bottom to be on the receiving end, and that since technically the top is the reason why the bottom is tired and exhausted the Top wants the Bot to wake up clean and fresh after such a wonderful night together.
(Hope this clears some of your 'whys') (>0<;)
For everyone who ever decide to write a BL story.
Please don't make the seme clean the uke after sex. The heterosexual men dont bath their sleeping partner, and the gay ones dont do it either. Its super weird.
Also, we dont use fingers to get the semen out of the ass, we shit it. How does using fingers help at all...
I understand its fiction, but considering it is constantly used in BL stories, it seems like the authors thinks this is actually a thing....
