Keep in mind that even despite our recommendations and preferences, its your game after all.
To summary what I see as NTR or not its basically, is it a person? if yes, then its ntr (the pool scene its light ntr, thats why I suggest that the first time you push im away with NTR off, he doesnt get closer again. Groping isnt ntr at all). And with monsters its kinda complicated, depends if its rape (Tentacle) and Salvor enjoys it or not. If she doesnt enjoy it or seems not to, then it shouldnt be considered NTRish, if she does (like the too many salvors event) then it should.
I guess by "NTRish list number too high" I guess you mean that some people complained that they are quite significant amount of NTR scenes or that a lot of them are considered NTR but not disabled by toggle (Futa and pool). Or by number too high you mean that you added some scenes that despite featuring other Salvors it isnt really NTR? (if you could detail this a little bit more ill be grateful!).
Don't feel pressured, no matter what you do Ill still play the game and I know a lot of people will, Ill eagerly wait for that Tish x Dispatch and Salvor x Dispatch tho!
