Deep breath.
She's going to try to explain it better this time in case maybe Maillol would understand it if she explained better.
"Keltham noticed that no one indicates how they feel during classes by looking distressed when they don't understand what's going on. That is not what happens in dath ilan. He inferred from this that no one would indicate how they felt during sex by looking distressed if they did not like what was being done to them. He - automatically assumed that we wouldn't want that, and concluded instead that we must have some more complicated way of communicating that information. I was uncertain whether to make one up or to try to explain to him that normally people just don't worry very much if their sex partners are invisibly distressed. The problem with trying to lie to him is that which facts about the world are inferrable from which other ones is completely sideways for him, and I don't think I could accurately track all the inferences he'd make from something I made up.
I'd rather as much as possible tell him the truth because of the sideways inferences problem but I need guidance on which things it's most important to keep secret even at some cost in our overall plausibility and coherence as he experiences it. And I need to solve this right away because I think if I just sleep with him, which I'd really really like to, and then later explain the thing where some people solve the inference problem by simply not caring how the other party is doing he won't endorse having slept with me without knowing that."
