Does anyone know what that little membrane they keep showing in yaoi is… like in the but...

are talking abt the perineum? the skin between your balls/vagina and ass?

prostate where man feels pleasure

usually in omegaverse it would be the cervix/womb (which is very painful and not possible irl pls ignore yaoi logic) if it’s between an omega and an alpha. considering wooju is a beta i have no idea i guess its just meant to show that he’s in deeper than he should be?

I think they're asking ab when the author draws the inside of the hole you see like a kind of fleshy line. And it seems the seme is going through it or smth

Then it might be where they enter the big colon? Is it logically possible i don't know but anatomical wise that should be it ╮(￣▽￣)╭

Probably the entrance to the sigmoid colon

I googled it that’s fucking terrifying my gid

LMAOOO
