don't worry for him, there is no conscience left and this isn't a guy, but a mechanical skeleton with fleshy parts arounds with no consciousness left.
Maybe this is more a cyborg than a robot then, I don't know, but it is still a machine.
For me the terminator for example is a robot, but he still have flesh and bloody parts around the metal skeleton. In my gigolo's case the fleshy parts might be real flesh, but the overall character is still a machine.
About the smell, the engineers who build those robots found a way to use flesh without having it decay, the goal is still to have something useful to women even if it is a bit creepy. The makers want the product to earn them money, and for this they need to have customers
I can see why you don't see him as a robot, maybe my own definition of robot isn't accurate, but I don't think that a robot has to be all in metal, even on the outside. The robots in A.I for example are really life like on the outside, with synthetic tissues that really looks like flesh. The terminator also looks like a real human until it is wounded, and robocop has a real human face attached to his robotic parts.
