I think about the like... legacy of it all.
Marius also hates to feel things. That's his stoic Roman thing going on, where he fears that by feeling things he will lose control of himself.
So instead he makes Amadeo feel everything.
And then nothing is felt, really for the next 240 years until Lestat swings in and makes him think "yes I can be desirable please desire me," but that secret disgust he's never been able to name is its own obstacle in begging Lestat to desire him back. And Lestat is also struggling with his own feelings about being desired and claimed at the time, so they're just two planets in orbit begging to be loved but not knowing how to do it.
Then we come to Loumand, and the desire there is very real and intimate, but once again Armand only knows how to present himself as desirable and that hurts just as much when Louis struggles to dedicate himself to that companionship.
With Louis withholding his feelings and making Armand feel used, and then with Armand betraying all of the trust Louis tenderly gave him, they both just ended up in a cycle of self-harm and love. It hurts Louis to desire him, and it hurts Armand to be kept solely for desire.
So when we come to Daniel and Armand demonstrates the deepest love he knows, he echoes what he remembers of Marius. His doll that feels all things. But it's less about the fear of losing control for Armand, and more about how alienating pleasure is for him, so by distancing himself from it (cuck chair), he is preventing himself from sinking into the self-harm of pleasure by making Daniel experience all of it himself.
