Fantasm comes again (1977)

Libbie is assigned to her paper's sexual advice column, "Dear Collete". She is taking over the job of Harry a crusty old journalist who shows her the pro's and cons of the job while running on a tight deadline to get the column finished for the morning's paper. During the course of the evening they reply to a wide variety of sexual experiences submitted by the readers, some these include, sex in a threesome at a drive-in theatre, sex in a gymnasium, and sex in a library where the "Silence Please" sign gives the male librarian an advantage over the female readers.
