Whew ok so lots here, let's see
1: Ideally I think Dukeporne has maybe 1-2 more acts, there are still a good number of events already drawn and waiting in the games files for me to get to. I think Post Dukeporne or concurrent with the later parts of it I Might make another parody game in the same vein, since I've already hinted a bit at an Elden ring spinoff's potential for horny content too.  That besides I would like more original content and less parody in this format and am considering how to go about it. 

2: maybe to the boyfriend, but doubtful that I would put particular emphasis on being unfaithful as that's not a topic I personally find joy in, as for relationship management and points, 

3: it's a possibility although with about like 9 months of playing with this sort of system now I can Definity advise that there's an exponential increase in the difficulty of managing those kinds of variables the more that there are.

4: I'm not an especially kinky guy, and my personal preference is enthusiastic consent tbh so  I would tend to expect much of the same tone as is in the game currently, but the phrasing of this question is very confusion to me, plus the game does already feature several branching paths, 

5: Ideally I'd like to get the next build out before the end of the year, but the holiday season can be hectic so fingers crossed.

5.5?: This entire game was built in renpy, Between a close friend showing me the ropes, videos from youtube especially from "Zeil learnings" "Thundorn Games" and "Visual Novel Design" I was able to pick up the core coding language pretty fast. basically all assets were made by me via clip studio and procreate
