Just trying to maybe clarify on this using your analogy: I would say your "pizza dough" is your story and the "toppings" are the sexual content available. The dough is irreplaceable while toppings should optional which you seem to intend to do.
Now let's talk about a controversial topping: Pineapple.
There are those who like it, those who are indifferent to it and those you detest it.
There is nothing inherently wrong about having it on the menu but for those who detest it it will never be an "option" and some of the indifferent people might even try it once in a while. But it takes time to prep toppings and there is only so much time available.
Now there are a few pizza shops available and one can only eat so often so that those detesting pineapple might eat somewhere else as there's more of other toppings available. Also some toppings tend to "spill" as some sexual content without it reflecting in the character(s) open to it would be very weird.
Lets take the scene with the sexbot as an example. There are 4 variations of that scene.
1. No sexual content (Dough only)
2. Sex with the Bot (Topping 1)
3. Futa Threesome 1 (Topping 2)
4. Futa Threesome 2 (Topping 2)
Those took work and all participating characters had to be open to the outcomes it would have been weird if the futa character would have been disgusted by the sexbot and then participated in the threesome. Now someone not into Futa might feel like "too much" work was put into content that they will never want and move on. (Or at least are less likely to support)
I personally think this is an example for a good design for this kind of decission as it gives full agency to the player. If none of the sexual option are to the players taste he has the option for nothing sexual to happen.
As long as this is the way going forward I am okay with not all content being to my taste, if the "spilling" of toppings I might not like is not to egregious. Going back to the analogy: Say I don't like green pepper and I don't like pineapple. Now I get asked if I want green pepper on my pizza and I decline I don't want automatically be served with pineapple just because I said no to green pepper.
I hope these discussions here aren't discouraging as I like you game so far.
Best of Luck
