The Celestial Bed is a 1987 novel by Irving Wallace, revolving around scientific issues of sex.
[1] The title refers to the "celestial bed" marketed by the 18th century sexologist James Graham.
One of the theories the book addresses is that certain individuals are ill-adjusted to normal sex, and that this can have grave consequences.
The book also discusses whether sex technicians — the people who provide the hands on learning — are prostitutes.
The name of the book comes from a famous quack cure for impotence and sterility advocated by the "doctor" James Graham.
