Anyway I don't try to overthink it, because mpreg unrealistic trait, as well many others (like dongs bigger then characters, for example). I treat it as magic: it's simply that way, no need to question.
Overthinking is what I do, lol. Being able to really think through it and imagine it allows me to better articulate it so others can get a fuller and more appealing imagining of it as well. So yeah, it can be easy to say "it's magic", but you can also go with things like "males could have a womb connected to their ass like a cloaca" or "the male body pushes the baby through the analogous vagina, the urethra", which in turn can be described as "you feel the child push out from your womb into your rectum" or "the child squeeze into your urethra", etc.
I'm seconding the ability to turn off some of the more extreme kinks. I had a love-hate relationship with the unbirth prostitution encounter because it gets you a lot of money, but the only way it could be further from "my thing" is if it was rapey and/or bloody. How opting out generally works is that scenes are tagged/flagged with their contents (watersports, anal, etc) and if the user encounters a scene with a blocked fetish, a generic replacement is given, possibly even just a message saying "Scene was skipped for containing ____, which you have blocked".
The problem with that is it can really ruin the "atmosphere" and "pacing" of the game. It's totally possible, sure, but if the Mistress is half about unbirthing, it's either more difficult to segment the paths for her, or I would have to remove her entirely which means if she has an item you'd need elsewhere, I'll have to figure out another way to add that item. It's just a lot of overhead for something that the player can just click "Next" through and never return to again.
Something that might be cool to add is affinity/rep for the various cities. You automatically start out with some points in your hometown, so the events will have people regard you with familiarity; go to a new town, and people may act differently towards the outsider, but if you keep doing stuff there and helping out, you might become something of a celebrity
That does sound cool, but unfortunately would take a lot more work to implement. There's a lot of things like that; followers, dynamic townspeople, new features that completely alter half the scenes in the game, all of which would take a lot more than I can currently put into the game. As it is I'm mostly just dabbling with game mechanics as I'm having a hard time bringing myself to write new full events xD
