lol for the anti-NTR people, they hate girls having anything to do with other males at all - a flashback is just as bad for them. And some are even as extreme to hate it if a girl isn't still a virgin/had previous relationships before they met MC. Somehow that is also considered NTR to them, even though the girl wasn't theirs at the time to have "taken away" from them.
I personally dislike the way many devs approach lesbian content, with the assumption that everyone likes it and it should just be automatic. I agree with others that just because it's a girl, doesn't mean it can't be NTR. Use a real life example, would you not consider it cheating if your girlfriend/wife was having a relationship with another woman behind your back?
I wouldn't get caught up too much into it, though. Just tell the story you want to tell.
while i don't mind a character having a past (like irl people have life before meeting you) i always feel it sound wrong to play a game to fap and having the li have sex flashback with other dude ... wouldn't you feel pissed if your girldfriend or wife was having flashback of previous relationship and detailed it to you ?
having a short summary without name or detail seem ok but not once you get details (player see a complete scene where you can even tell how many time the girl was pounded and the number of hair she has ...) having it forced upon you is probably what piss the people that aren't into cuck fetish
on the lesbian content i have mixed opinion, while i like watching it it sometime is just that lesbian sex and if i play with a male protag it's so play a straight story where i play as a male that have sex with women, i have nothing against the girls being bi-sexual, but when the relationship is "ambiguously" turning to have a heavy lesbian side it's stop being realy pleasing to me, i think you probably agree that threesome is nice, some lesbian preliminary is too but get ticked off when the girls start having relationship that exclude intervention, presence and or consent of the protagonist ? (and that's what lots of dev seem to not understand, like the dev of "mainstream" ntr with a small dicked nice dude being cucked by a gym chad half pony black dude >< ... always thought it was racist to both withe and black to have those stereotype being used so often :/)
the real problem is the fact tags are extremely vague and poorly used, making it hard if not impossible to exclude those a user don't want to see ... if you want a funny exemple, take futa protag, personaly i have no interest in gay content (as in two or more individual with a penis having intercourse :/) i should be able to find that by simply excluding the gay tag but my results are flouded with futa x futa and futa x male and futa x trap and with all dev going on the skipable or avoidable scene to please crowd it's even harder as you still need to look up at least the game summary and dev note ... to know if you must ask if the avoidable scene are avoidable or skipalbe because as tag have different meaning than the word they use to represent themselves when used here, word in description and conversation aslo have different meaning and need to have confirmation -_-
in the end i agree with you, if you think about it too much you just loose ^^ before starting a game i read summary, dev note and a couple players reviews to be at least 50% sure i won't come back to the thread just to spit disagreable comment at the dev ^^ (here i still had doubt but not anymore after seeing the number of people ranting anout the plot) game seem a bit sloppy abest and not the enjoyable sloppy, the dirty sloppy with dev trying to please everyone but only tweaking his actual plot by using game mechanics that are actual 4th wall intervention and not canon reasonable content
btw to go back on the "previous to mc encounter sex", and "some lesbian sex", they feel as strange to me as the straight game where you the straight player is forced to spend literaly hours watching the mc tacking shower alone and jerking in his bed ... they seem like a failled concept to me :X
