Totally agree with Rehwyn ... but as the dev notes, there's an element of the AVN community -- an unfortunately loud if not necessarily big one -- that likes to cause disruption based on anything that even could be considered within the same galaxy as something that actually fits in the NTR category ... and then once someone throws up the red flag, there's the "Ooh, disruption! Let's add to the noise" crowd that joins the fray. Then of course, all the fans get up in arms, and the race is on.
There are many threads I used to frequent that I now just poke my head in on occasion because of all that.
Anyway, for me, there's nothing wrong with characters having a life before the timeframe of the game you're playing, nor characters in the game that you're not involved with having their own life and crossing the MC's path. NOR any consensual sharing, if that's part of the story.
There's also nothing wrong with people staying the fuck away if that's not something they can handle.
