Gender of "The Ex" (Posted from ATF thread by request)

I have come to gain some respect for how "The Ex" quest handles the children. I am aware the main point of the quest is the children, and not the spouse, but I have noticed one weird piece of logic, which leads me to make a request.

• A player with a penis will have two female children and a female ex.
• A player with a vagina will have two male children and a male ex.
• A player with both a penis and a vagina will have a younger male child, an older female child, and a futa ex. Alright, still makes sense.
• A player with no genitals will have a younger female child, an older male child, and... an ex who's always male? WHO MADE THE BABIES THEN??

I humbly request that, in the case of no genitals, the ex either be random or the opposite of the player's gender choice ("femme" or "masc") in the government-issued ID. I'm aware the ex themselves are not the focus, but I have a soft spot for letting them move back in so we can be one whole family again, while also desiring one son and one daughter (which simply makes for a wider variety of incest content). Suggestion forwarded from the ATF thread upon request from VoidSquad.
