There isn't supposed to exist any forced sex scene in the game , if you found one (or more) let me know what they are, I could have made a mistake or there might be a bug.
Absolutely, no problem, here is a full list of scenes I didn't like on my attempted monogamous playthrough and I will make it actually extensive, some might seem super cringe, others will be very serious. I will divide it into two categories:
Not SUPER serious but still very bad, because I consider ALL of this cheating as well, if you think it is not imagine your GF doing this with another dude and you would call it NTR very fast:
1) In the tavern Isabella tries to kiss you and you can deny the kiss. Later in the village she tries to kiss MC again, we can deny her again, but she kisses MC anyway - sexual assault, I know it's rofl, but it is what it is. Later in the tent she tries to kiss MC AGAIN, and here comes the very WEIRD part, you can deny her only by telling her that is because you think she is your sister, because of course MC is a horndog and would only deny her because he is not cool with incest, not because he has a GF. And then the FOURTH time MC kisses her himself. So we started out with just being able to deny her, went to being able to deny her but she ignores that and kisses MC anyway, to NOT being able to deny her at all and MC just kisses her himself, cheating on his GF.
2) He is completely chill Isabela sucking his dick in a dream.
3) He lets Lust kiss him.
4) He lets Princess Enainia kiss him and he almost has sex with her and the dialogue choice that makes him not do it he feels like he really wants to and has a kiss with her again. Not in the super serious category because it is a dream.
5) Kisses the librarian when he is back at college and he lets her.
6) Ayna kisses MC before battle with Gluttony and he lets her without objection.
7) Tenizha and another girl proposition themselves to MC and his decline is: ''Maybe next time'' As if he is a regular visitor to prostitutes. I never used prostitute services.
Very serious:
1) MC gets properly raped by Carilielle at the church. Not cool. I don't mind rape in games, I really don't. But I am not fond of MC getting raped, specially when I am trying to do a monogamous playthrough.
2) MC and Katriona giving each other oral under the influence of spores. This is another outright sex with someone who is not his GF that you can't avoid.
3) Mother has sex with MC and he goes along with it enthusiastically, and I got a strong impression that in this case it was not a dream. Keep in mind you allowed MC to deny sex in dreams before ( if this is a dream ) with Enainia, why is this one forced?
Side note:
In general MC is a complete horndog, I REALLY dislike how he constantly talks about girls being hot and not being able to resist them in his thoughts. Let the PLAYER decide who MC finds hot, don't make him a canon horndog if you want wholesome relationships to be possible. Because when MC is drooling over every girl it is cringe. Because every time a girl flirts with him or touches him, or is nude near him or kisses him he is like: ''Omg, she is so hot... I.. I..'' etc. And he is completely docile every time someone wants to have his way with him in a dream or otherwise just letting the girls touch his dick however they please and do with him whatever they want, how he is completely chill with girls just getting into the bath with him when he is naked. Sometimes feels like I am playing a slut simulator with a male MC. You might think this is nonsensical but again, imagine you have a love interest in a game like this and she is cool with other dudes beside MC kissing her, having wet dreams about them, being naked around other dudes when they get into the bath with her, constantly drooling about other dudes in her mind etc. Even if she is not outright fucking them, you would still call in NTR wouldn't you? Well when you are trying to do a monogamous playthrough it is just as bad just from the other side.
Side note about Mida:
What the hell happened to Mida throughout the whole game IF you don't ask her to be more slutty during tavern sex and don't raise her Corruption at all. She starts the game by telling Fanny to leave her alone when Fanny hits on her in the beginning if you leave her to her own devices, but later becomes super enthusiastic about sharing the player out of nowhere. Asks the player to take virginity of Koneko and is open to sharing. Why? What is the point of corruption at all? I had maximized love and zero in corruption. What is the point of these corruption points if my GF is going to be a cuckqueen regardless? Why isn't she monogamous and protective of the MC at zero corruption and max love? Though this is more relevant to ACT 2 where she becomes PROPER sharing / cuckqueen no matter your previous choices, because nothing is more romantic than your GF who you tried having a monogamous relationship with conjuring illusions of other naked girls who are not her in the bedroom, right after you denied having a foursome with them.
This is the summary of ACT 1.
Final side note: I don't think you will actually change any of that, it is too much effort only for a few people like myself that actually enjoy monogamous relationships, and just to make it clear, this is a good game, this game is very good as a fuckboy simulator. Just something for you to maybe keep in mind going forward when you make dialogues in your future projects, as a lot of these things are super easy to avoid: ''MC says no, you skip, doesn't effect the story, boom done.'' And ask MC before all the groping and kissing and nakedness starts.
