1: (A,b,d)
2: A,E,I
3: A,D,F,G,H
4: No opinion/ all good
5: A,B,D
6: Gonna go in depth on this one.
A: Literally never. Tattoos are a instant turn off for me.
B: Fit to Fat is great, so this in tandem with other elements is great
C: Ya love to See it 
D: indifferent
E: Nice, but not ideal
F: meh
7: As mentioned, fit to fat, belly drops (pulling up shirt and having tummy flop out) clothes ripping, minimal full nudity (save it for later, make it meaningful.) Size comparisons, like in Cowgirl Casino. Belly slaps with jiggle are peak. I cannot/will not be swayed.
If the game is made in unity and DOESN’T capitalize on having a gallery with interactive physics, what are you even doing. Like not having physics is fine, its complicated and i understand, but you’re gonna have physics without the option to view it outside of gameplay? why though? This is getting off topic so i’ll move on.
My Achilles heel has always, and will always be gamer girls. I love having a character i can interact with and relate to outside of my player character, so thats always a plus. Childhood best friend is a good trope, too.
And, once more for good measure,
Tummy supremacy is, in fact, the 20xx of Feederism. You’re all in denial if you do not accept that tummies are the pinnacle of the WG experience and to argue otherwise is sacrilegious.
That being said, you NEED to have other parts too. Realism in body type is a must have, unless its, like, an artstyle thing. Cartoonish ballooning is a no-go for me, i know others like it but for me its just takes me out of it. This extends to All parts, so having it be evenly distributed (with the tummy at least pronounced) is the go-to.
But hey, thats just my take.
