Why not, after all? It sure seems logical to me. Don't forget pets, while we're at it.
In C.S. Lewis' third installment of the Space Trilogy, "That Hideous Strength", Ransom relates the marital relationships and reproductive processes of those persons who live on the Moon. Seems he was about seventy years ahead of his time.
MAASTRICHT, Netherlands, Oct. 11 (UPI) -- The University of Maastricht in the Netherlands is awarding a doctorate to a researcher who wrote a paper on marriages between humans and robots. David Levy, a British artificial intelligence researcher at the college, wrote in his thesis, "Intimate Relationships with Artificial Partners," that trends in robotics and shifting attitudes on marriage are likely to result in sophisticated robots that will eventually be seen as suitable marriage partners. Levy's conclusion was based on about 450 publications in the fields of psychology, sexology, sociology, robotics, materials science, artificial intelligence, gender studies and computer-human interaction. The thesis examines human attitudes toward affection, love and sexuality and concluded that the findings are just as applicable to human interaction with robots of the future as they are to the relationships between humans of today.
Excuse me, did that say 'sexology'?
