"Non-stimulating" and "not stimulated" sounds like there's no sensation at all.
I agree that that deduction would be something to be avoided.
The pleasure of floating on a calm sea
But this would be only one such pleasure and we'd likely want to avoid "floating" metaphors as well, unless we are ships, because floating is what ships do. I would say "floating" is going to evoke "mindlessness" or "total inaction" unless we are careful to exclude that. And that's where the kinetic language gets blurry, if for example savoring memories is kinetic.
We're humans, and what we're looking for I think is something the conveys "doing anything and everything that humans do when they are not 'excited' but also not in pain." We're looking for a word that describes all normal activities of life where we aren't "excited" but we are still functioning normally. I would think this is what Torquatus is pointing out as the answer to Chrysippus' hand hypothetical. A hand is which not being stimulated or excited or massaged still falls under "a hand in pleasure" so long as the hand is not in some affirmative pain.
