Seriously, sex is the driving force behind most things regarding social interaction. What will happen once we develop a sexual android that looks and acts exactly like humans, that any person can buy.

Will (most) men have a reason to go try and find a real woman and play the whole social game of running behind them just to get their attention over other men when they can just go and buy an android with a physical appearance tailored to their demands and is willing to do anything? (Which also has no legal rights and doesn't give two fucks about preserving it's existance, so that might appeal to the debauchery of many being able to carry out their otherwise illegal fetishes without any consequences.)

Will society collapse?
