Hottest take. Give them 3 holes
The butt, vagina, the dick for pissing and cumming
Tbh I kinda liked the world building of calling them "omega parts" cuz yeah makes sense in that kinda universe it'd be that. Also yeah bl authors give us every part, what's stopping you
My joke answer would be bc they know it would be too powerful! My real answer would be a mixture of misogyny and transphobia which is commonly seen in bls, most often there’s a heightened awareness that the bottoms have a denial of bottoming bc they are MALE and have PENISES so that automatically means they like to stick their dicks in things. These authors would rather have these omega men push babies out of their assholes then have a vagina bc that in their mind would take away their manhood bc to them bottoming in any universe is demasculizing. To them giving a man a vagina would mean he isn’t a man and they can’t have that so they must poop out babies instead and have a uterus in their colon?
Not the colon uterus
But yeah I think that's the crux of it is that adding the third part makes them "women" in their eyes
I love that they have both a vagina and a dick and now I’m wondering why bl authors don’t give their omega men both as well? why are these men giving birth from their buttholes cowards! Give them women and men in omega verse both genitalia!! ლ(´ڡ`ლ)
