Would you have a relationship with an android?

They wouldn't be like a prostitute you didn't have to pay, unless they chose to be. They would be no more likely to be sluts than humans. They would notice if you were a nasty fat slob and have their own standards for attractiveness, they're not blind. They have their own desires and wills. Due to the complexity of their minds, with each aspect of it depending every other, even an android that was conditioned to be a sexbot may change after being exposed to the world, and regardless still wouldn't take kindly to being raped any more than a human slut would. Because the android brain fundamentally relies on environmental considerations and new behavior over time, much like a human's, anything designed strictly as a sexbot would also be essentially retarded. Trying to reprogram an android to be a sexbot would basically ruin it, as its brain model simply doesn't allow for that without the way it works being changed on the most fundamental level. That would be the only way to ensure it would stay in that role.
