Comment: It's not clear to me if you can project Biblical ethics on something that was completely inconceivable at the time it was written. At best, your interpretation is nothing but speculation of how sex robots would appear in the minds of the Bible's ancient Israeli contemporaries, an interesting anachronism that highlights the dangers of this approach.    

Who is to say if high tech masturbation diminishes your relationship with God or others, any more than the lower tech current forms?  Is the technological sophistication of the toys what makes it "unethical", rather than the act itself? If it IS the act rather than the toys, then that battle's long lost.
