Or you can act like a person with some some morals and don't accept sexual favors in exchange for your help.
To me is not about pronouns, it's about helping someone or taking advantage of their situation.
This is not exclusive to Mason path by the way.
In real life, I absolutely agree with you. Don't take advantage of people, don't misgender people, and don't do thing's expecting anything back.
But in the game, it seems like the most content is gained by being decent but with a lecherous edge.
Meaning you help someone but also take what is offered. For example, the gabby situation, you get the option to eat her out and start her route if you pull her back down and start fondling her, IRL I would never do something like that to someone, but it was hot and the best option for the romance path.
It's a weird choice, but that is probably going to be my cannon playthrough, be nice, but take what's offered while trying to treat them right. If more content gets added for being an actual decent human being, I'll go that route instead.
Side note: I really, desperately want to have a conversation with Mason about how they see themselves and more to the point their sexuality. This would go a long way towards if I'd actually have a relationship with Mason or not.
As others have noted I have a feeling misgendering Mason and refusing to accept her as a him will probably lead to a bad path for Mason but I kind of hope we can influence them into a more they/them situation where he doesn't mind being a "good Girl" for Daddy.
I also still really want to know if Mason changing their backstory depending on the route is just Mason lying to us or if the choices actually change the character's backstory?
