Most men are not much into the idea, either.
Intimacy is something very human, something most people are not ready to trust a machine to do, even if it's capable of visibly empathetic reactions.
There is a desire to connect with another human being, not programmed to like you, but actually choosing you freely. It's what people call "feeling it real".
Most folks I have seen pushing for robotic partners are incels craving at least some form of closeness - having something like this might be better than nothing.
Also, dudes, let's be real: would you put your dick into a machine much stronger than you? Something goes wrong and you don't have your precious parts anymore.
