It is really hard to have an argument when you purposely only interpreting something the way you want.
and twisting and shaping What we know , in a way you want to back up you argument.
Enlighten me, and point me to the direction, where it was stated as Fact that Chad and Sage was never intimate with each other? And I'm the one who use Extreme arguments?

.
First of all Sage, decidedly assume that Chad cheating on her with an another GIRL. The fact that in her mind its never even crossed that its actually a guy is speaks volumes.
She upset, when Chand only kiss her on her forehead, lashing on to him, that When was the Last time when we get intimate? and Not that, they never was, before.
Does Sage strike you as a person, who would stick with a man for 2 or 3 years, with out any Sex. Her Frustration comes from that She not getting what She used to get.
Combining this with Sage explanation about how in her family " feelings" are some kind of Tabu, it's clear that her relationship with Chad was not something Romantic cuddling and hand holding all the time. But she was getting something out of it.
Young Sage, making Remark on Rusty's "pocket", eagerly staring at it

But her pussy gets moist, When the Big Bad Alpha Chad show up.The coolest guy in the school, Who then plays the stereotypical Badass asshole toward her, whats makes her even more wet.
When MC arrive, Sage and Chad relationship already hit the rock bottom, that's when the story start. The game given us enough information to understand the situation. Without us, needing to see what they were like. Because whats matter is what they are now. Thats where the story start.
And even if you playing this path, it's obviously presented , that in any given moment, if Chad Say, : Hey Sage time for your daily dick sucking . - She would have dumped MC without a second tough.
There is nothing lacking there, we have all the necessary information.
Josy Maya had to be shown, because we didn't have the information.
And the fact that Bella did not kiss her hubby is
what makes the Flashback suspicious. She was sent home for seemingly No Reason, which keeps the Mystery around Bella.
and I think that is more the reason, than just She being asexual, or DPC is afraid of controversy. Which is more in line with DPC "Style" if he has one , this is more what we assume form DPC.
Keeping us keep guessing, keeping us in a mystery. If it's simply just, Bella kissing with her husband in her workplace, and she was sent home for it, - which is also a bullshit reason - , but in then its is just Thats it, and nothing more. It would be just a nice lovey-dovey scene, and nothing more. It would add legit nothing beside that. And He does not use the Flasback just to add nothing to it .
- Hey Bella was happy with her husband, cool, Yeah, We know, We see the photo. So What was the point of this scene again? -
See where I'm going with ?. Anything more to add to you secret desire NTR Fetish, ?!
at this point I think I'm kind of debunked almost everything, that some of you guys disguise as a secret NTR fetish, or hoping to use it as an ammunition for new kind of Trolling .
Lostanddamned . probably one of them who would gladly like to use this as new weapon for Trolling, He lives for Trolling, and the Jill Smile is getting a bit old now. But an NTR is a never ending amunition, obviously he would love it to have it.

I just never realized how many of you out there who want the same.

I still love you SomboSteel
