Omegaverse doesn't really have ground set rules especially when it comes to how male omegas work the authors just mess around with the story and do wtv they want
depends on the author actually, read a male omega x male omega, ml o x fml o, where both setting can get pregnant, but also a setting where male omega cant impregnate anyone if i rmb correctly
Mostly Yas! As long as there's a dick and womb it's possible. That is unless author tweaks their own world building. One best example is Mc's parents in DASH
So I was just thinking.. can a male omega get a female beta pregnant or what
