I'd like to think about Terzo and Omega's and Copia and Aether's relationship for a hot minute, because it's simply not normal.
Sure hooking up with a ghoul or ghoulette isn't really frowned apon at the ministry, it's pretty normal to hear or see it for yourself. But sex is just sex after all, what Terzo and Omega have is... intimate. Holding hands, cuddling, breif kisses before a ritual, and just over all a pretty humanly domestic kind of love.
Same goes with Copia and Aether, they have that same domestic type of love. Except without the sex, Copia doesn't feel like sex really like... gets him going. He's known he's bisexual, for awhile now but he never really realized how much sex is a turn off for him so he's probably on the asexual spectrum.
Anyone with a brain can see that these human ghoul couples are more in it for the romantic aspects than the sex itself. The ghouls and ghoulettes can tell that Omega and Aether are (poorly) attempting to court their respective boyfriends. While it's not uncommon to hook up with a ghoul or ghoulette it is usually not intimate in the way Omega and Terzo are. And it's definitely not like Copia and Aether's relationship which is all love and support.
