Well... I think mine could do pretty well on steam, fetish-wise, and even Patreon. I'm not worried about that. The ONLY fetish I regret leaving out, is rape, but it is what it is.
But Real Porn is a bad, bad choice for a game, one aspect I deeply regret using when I was in the middle of the development. Fortunately, my next game won't have this problem.
Steam is still off-limits to me, the only graphic allowed there would be Daz 3D, or 2D by an Artist (AI is also out for me, my PC is too old). Honey select, Koikatsu or Sims 4 (my next idea. Originally, Grizzly Grove was going to be made with Sims 4 characters) based games won't do on Steam either, copyright issues.
There are many RP games on Patreon, I hope mine hold up until I start the development of my next project.
A great game developer once said, "You won't make a perfect game out of the gate. But if you keep iterating, keep applying what you learnt from the last, next game will always be much better."
(Also the reason it's not ideal to make a large scale game as your first project).
IMO, one of the standout of your game, is the very well curated porn that fit perfectly. (Many RP just slap together some random porn that fits in the action)
I wouldn't regret it at all - unless you really depend on the largely limited monetisation.
Not sure about Sims 4, it's too corny / uncanny, creates a funny / not serious atmosphere - unless that's what you are going for.
And Honey select / Koikatsu ... ain't them for girls / twinks? Never saw a musky gay game using them....
AI art ... I yet to see a decent AI art game that's not boring / generic / uncanny.
That got me curious. I'd assume you are well connected / good at networking?
But no chance for working with an artist?
I saw many furry creators collaborating to create games. Tho doesn't often hear such thing for non-furry porn games.
... Come to think about it, there's really not many western realistic-style bara games, even when it's huge in Japan.
Most 3D are also not good, either too Uncanny, or too Twinky - limitation of the 3D tools I guess?
Only a few are great, like Cloud Cuckoo Land, or Hornstown.
Or it's time to pick up a new skill, talented creators are often of many skills
