yeah your locked out of Logan's heart if you don't choose him, but not choosing Bernard doesn't lock you out of Bernard's relationship, and or you can still date him if you chose Logan in the quest.
the questline for the curse of lust is unaffected by your Lewd fame, but the lust of the warriors and acolytes does affect it. if together they equal over 10 and you choose to hide the corrupted lake from Othra and suggest she reveals the pure one to the tribe and let's anyone go in it gives the evil ending to the lizard's questline. not saying how exactly it's evil but you'll find out should you try it. plus, an extra thing, Rhot despises you if you corrupt the village by doing that.
also, it's no problem asking questions, your just tryna be prepared for future stuff so you don't do things you wouldn't wanna do on accident! and I think you wrote fine lol. it's all understandable and is written better than people I know irl who have spoken and read the language since they were kids XD. I'm one of those people but ya know-
