Their official stance [1] is:

> You can make same-sex relations acceptable, but marriage will still only be opposite due to historical constraints.

Other than their official stance, I wonder if it's because they'd need to script in the in-game church's (presumably negative) reaction to this. Also there doesn't seem to be adoption in the base game, so maybe they didn't want to hand the player a quick path to a game over?

The game simulates historic reality, and that reality was that marriage between nobles was mostly political and about consolidating land and power rather than about sex, love, or attraction although breeding was also intrinsic to marriage for the same reason. Marriage is a major game mechanic with much of the UI and playflow dedicated to finding the right spouse based on a wide range of conditions (family status, demesne extent, breeding traits). Doing same-sex marriage would require a massive overhaul to much of the game mechanic, not just a simple gender swap for the intended spouse.

Because the love/sex/reproduction angle was separate from the marriage angle, the game already has very deep support for all variants of human relationship when it comes to lovers, concubines, and uh, other special situations and it's very historically accurate. Homosexuality among nobles was not uncommon in the middle ages and the game supports this directly, but marriage had nothing to do with love or sex.

I went to Glitterhoof's chambers and gave him a good tumble. It is good to be the king.

If it were me I'd just let same sex couples impregnate each other, regardless of sex. Sounds like a hoot.

I'd also add furries and dragonkins while we're at it, because why not, it might as well be a fantasy game

CK2 let put a horse named Glitterhoof on your council and then have sex with it, so that would be par for the course.

Was it ever clear if Glitterhoof was real, or a hallucination?

Note that this was unintentional ;)

A reference to Caligula?

I recall a Game of Thrones mod for CK2 that seemed like a very appropriate combination.

That's their official stance for the game itself, not the modding tools. I can assure you same sex marriage is probably the least historically inaccurate thing that would be modded in. Heck you can make yourself a kingdom of homosexuals.
