There's a disconnect involved with most of Savin's characters. He wants to invoke certain porno tropes which resonate with him and his central audience - feminization, forced TF, prostitution, slavery, polygamy, domination - that, once they enter a halfway realistic universe, become problematic. Most people were happy with Steph Irson whilst she was a cartoon on the TV. Whee she gets in over her head and gets fucked again, funny and horny too! Except when you get to actually meet her, it turns out she's a real person who doesn't like what's being done to her much. She's a zoologist who wants to travel and investigate interesting things about the galaxy, but her network prefers her getting repeatedly raped, because that gets better ratings. This would be an entirely reasonable extrapolation on her character in any other genre, but in porn it makes people clutching their dicks say "Woah hang on a minute - am I supposed to be fapping to this? Because mostly this is making my boner sad." Del! He's a boy, and he's been forced to feminize himself to pay off his debts, and he hates it but secretly likes it, and you keep forcing yourself upon him until he loves it, and he goes and gets big boobies as a result, and that's so hnnnngh. As long as you don't think about it with anything higher than your lizard brain. Then you wonder why there isn't any option to help him at all.
Writing entirely with your dick is fine as long as you're not doing it in a coherent, long-lasting setting. If you are, once your mind catches up, it is going to have to provide answers and justifications it dearly doesn't want to.
