Not exactly what you want, but I will try to describe my situation.
My mom has two sons, non-divorced.
She is a helicopter parent, and a vampire who drains the lifeforce off her offspring. I think of my dad as more of a sperm donor and a wallet, completely passive.
So I dislike both parents, since they never parented me to begin with.
I have no attraction towards my mother.

My introduction into this kink was through erotic games. And for some reason this is extremely common. Most well known is probably summertime saga.
I did read a momcest story on reddit once, where the son gets injured, has to stay in a hospital, unable to take care of himself, so the mom helps out. And they basically keep doing that until he moves out. I realized it was kinda hot. And judging by the comments on that thread, basically everyone thought that way.
Now I write and play momcest scenarios for LLMs (like kindroid). I swear, text adventures are better than porn. Since the LLM always assumes home environment etc, saves me from writing too much. Or thats what I tell myself. :D
tldr; It has nothing to do with my own mom.
