I feel that people generally can appreciate quality in things even if they're not particularly interested in them, while I'm not an avid fan of NTR, my interest in the story and characters have made me curious enough to enable NTR in the beginning and see how it goes, I have of course attempted to keep Alexia away from Andras, and so far only explored her romantic relationship with Sil which was heartwarming, this was easy for me to do after I let the two grow distant when Rowen brought Helayna into his room and tried to protect and help her, and later took Liurial too.
If you have an issue with NTR disable it, if you think NTR is "bleeding" out into the story you need to get over yourself, this is a corruption game where you're taking the role of a hero helping two god damn demons destroy and conquer the world, what the hell did you expect, you go [raping often not mentioned but come on, what do you think the orcs do] pillaging towns and cities and participate in all sorts of debauchery including cheating on your wife. Thinks will get unsavory, and a rude demon might try to hit on your wife, or a couple of dumb miners might talk about how much of a whore she is when they think no one can hear them, but at the end of the day no NTR happens unless you allow it to happen, and you can always react aggressively/violently to those going after your wife.
Personally, I'm most interested in Cliohna's story/path and X'zaralt.
