Can someone please explain to me this “if you don’t wash out the cum I your ass, it’ll hurt your stomach” thing that I’ve seen multiple times in manga? Have never been able to find anything scientifically or medically to really back it up, doesn’t seem to be a thing irl either. So why is this line so often in yaoi? It’s weird

    So I've read there's a strong urge to poop after doing it. Maybe that's where the "stomach ache" dialogue comes from.

    I have no scientific data to back it up, but purely based on my experience it really do hurt. Probably because it should’t be there in the first place

    this is how I felt when I found out you can't actually catch a cold or get a fever just by standing out in the cold lol

    I've read in batato, that if the semen still remain, it will be diarrhea or nausea
    because the chemical compounds in cement can irritate the intestinal lining

    I asked chat and it told me it wasn't exactly the sperm but the intestines being irritated or slightly injured after the sex and sperm kind of making the pain worse ig? Not a professional tho so I will not take responsibility if this ain't true

    i have experience and no, it does not hurt at all. it just feels disgusting after a period of time so its better to wash it

    there was one time i didn’t wash it out and had to rush back home. the cum will drip out causing friction and noises while you’re walking or running to the point it gets red and would hurt for a day seriously

    If you reach deep enough, you’re literally penetrating someone’s stomach — like that’s the “barrier” a top breaks into.

    Kinda gross to think about but think of it like if someone pushed snot up your nose, how would your body react to that organic matter being shoved inside you?

    There’s also the matter of whether the person penetrating actually has a big enough dick to penetrate your stomach so it really is a case by case basis

    It's so nice to see everyone help like that. My heart is healing

    I mean apologies for the overshare but in my personal experience it gives me an upset stomach type feeling. So unlike other BL exaggerations, whenever I see this in a story I’m yup get that cum out asap lmao

    ik this doesn't rlly matter but I'm p sure it would be the colon and not the stomach. If there was a dick out there that could penetrate the stomach it'd have to be like insanely long to get through the small intestine LOL

    specifically it's entering the sigmoid colon. there isn't a sphincter there and nothing is breaking, it's just a 90° turn at the end of the rectum.

    I find this trope extra funny with the knowledge that SK has like.... not only the smallest dick sizes generally but also one of the larger discrepancies between claimed dick size and studied dick size. make of that information what you will lol

    Yes, substance or anything that was put inside must be remove most especially secreted from someone, it can rot and cause discomfort and/or infection
