Totally random, but aren't you curious as to how pregnant guys work? Sure, they can give birth through c-sects, but it doesn't change the fact that they only have one hole down there. So where would the womb be? Bcos if there isn't a place to enter, how da hell would it even get out?
Okay so what I was thinking, was that the anus is kinda like a fork in the road. So the pathway that has the womb is closer to the front, whereas the pathway for the anal cavity is in the back. That way when the omega is taking a shit, the excrement doesn't get to the womb and possibly infect it. When their partner fucks the omega, they'll just hope for the best that they're fucking the cavity with the womb in it.
Forget abt the whole BL n romance aspect of this for a bit. If this was a shounen manhwa, i bet there would be a group of rabid fans thirsting over guwon like crazy. Especially the panels where he's covered in blood.
And i would be one of them ٩(๑❛ᴗ❛๑)۶
