Man And Wife / (Matt Cimber) (Andreas Kranich, Birgit Müller, Rosanna Romana) 
Proceeding from the premise that the ability to perform sexual intercourse is learned rather than innate, the film offers sex instruction for modern marriages. A brief prologue provides observations on the psychology and physiology of intercourse as a means for the expression of marital love. One male and several female models [two couples, according to another source] demonstrate 49 positions of sexual intercourse.
