There is the concept of a Sex Doll, or a Mannequin. These can be used for displaying clothing or for extending Masturbation to an elaborate system for increased Quality. 

There are also uses for a Life-Size Doll in Martial Arts Training. 

There is the concept of Soft Robotics, and Boston Dynamics making Android Soft Robotics that can walk on two legs, lift and place 20 lb packages onto a shelf with two hands, and independently perform Parkour maneuvers so Acrobatic they would be difficult for a Human.

With this advancement of this kind of Android, in mass production, it seems as if one may use one in the development of a Life-Size Sex Doll that moves like a Human, and is reactive to Touch and Body Language like a Human.

It passes the Sexual Turing Test when one could have Sex with the Automaton Doll, and be fooled into thinking it was Human.

For Martial Arts Training, it would be the same Dynamic.

It is training your every Muscle, and making certain not to hurt you. It adapts force according to its reading of your Body Language, Speech Patterns, Personality, and Emotional Wavelength. It knows how to train you because of Applied Mathematics in which it can solve these problems in an unwaveringly hyper adaptive manner.

It can fight. It can fuck. It is certainly a much better Mannequin than those that do not move.

In a Relationship with your Human Partner, this is useful, because the Android learned from Physical Interactions with both of you, and uses that Data to find a way to Physically Train both of you, with Sexual and Martial Arts Training, to be better Lovers for each other.

I see this as a matter of “Improving Life through Industrialized Automation.”

Even better, this Android is your Future Body. It learns so much about you over the years that transferring your Internal Organs to the Android may be a possibility in the Transhuman Concept of Human Immortality.
