Yep! You're absolutely correct that the open relationships are important to the concept and theming of the story— I did my best to communicate I was just talking about my preference there. There are ways of skirting around it more, but they would pretty universally be some kind of compromise to the main thrust of the game.
The fetish material you're exploring is actually an interesting twist on what is normally primarily relegated to games with a female protagonist. The concepts of communal pleasure, open relationships (that aren't MFFF[...]), free use, etc... exploring them in a male protagonist game is somewhat of a rarity.
I'll still check in on the development from time to time, because I think the work you're doing is high quality enough that it has the potential to break out of the mindset I'm usually in.
You're certainly welcome for the UX feedback, and I appreciate you taking it constructively!
