Man, I really like how SLARPG sorta like, approached it's tone in regards to suggestive content? Like, It doesn't pretend it's not a thing but it only very incidentally gets mentioned as an aside in a pretty nonchalant manner. It's not so aggressively "no it's not a porn game I promise uwu!" that it comes off as chaste, but it's just "yeah it's a thing that these people do and think about but that's not really the focus of this game."
for example, early in the game the main couple is in a room together, someone knocks and asks "are you decent in there?" before coming in. Or like, "I'd say this but Allison would make a dirty joke out of it." Stuff like that. I feel like if it erred too far on either side, it'd come off as weird and alienating and mismatched with the rest of the game.
