Oh I agree, but based on what's in the game thus far, I don't think she'd be particularly bothered about grabbing a bit of ass, or fucking Camilla on the dancefloor for example.
The system is barely established in game at this point, but I think it'd need to be more complex to work properly. I think say ass grabbing would probably excite Sage as a threesome thing, but I think if you for example you told Josy/Maya you still had feelings, that'd obviously upset her, especially with her abandonment issues from her childhood. I think it'd also upset Lily.
I hope Lily does get more development in the new episode outside of Lewd scenes, but between the Maya contract, Thanksgiving at home, Rio being kidnapped, I'm not sure if we'll have the runtime for anyone outside of J/M, Quinn, Rio and Sage with the divorce
