That was never a male female gender thing. That was always a secondary gender thing. I hate that so many people are confused because others just arbitrarily get into writing omegaverse stories and spread misinformation.
Not talking about you being a source of misinformation btw. ٩(๑❛ᴗ❛๑)۶ I'm just annoyed that someone possibly gave you and others wrong base info. Some rules of omegaverse change depending on who writes it such as can alphas get preggo or little touches such as each only get one mate or if one, alpha or omega, can have multiple. But it's always been Alphas ruts and Omegas heats.

Wait why does the mc go through heat while the ml goes through a rut even though they’re both males? Shouldn’t they both go through a rut??
