A magazine editor writes a best-selling book about female sexuality, claiming to be a psychologist but actually being a virgin herself. When her publisher sets her up with a charming 'boy-next-door' type, she tries to maintain her facade, leading to a series of comedic misunderstandings and romantic entanglements.

Sex and the Single Girl was a box office success, capitalising on the popularity of its stars. However, critical reception was generally mixed to negative, with many critics finding the plot contrived and the humor forced, though the performances of the lead actors were often cited as a redeeming quality.

• The film relies heavily on the star power of Marilyn Monroe and Tony Curtis.
• Humor is often found in the misunderstandings and attempts to maintain a facade.
• The premise, while topical for its time, results in a somewhat predictable romantic comedy.

Google audience: Audience reception is largely absent from readily available aggregated data. However, commentary suggests a mixed reception, with some appreciating the star chemistry and lightheartedness, while others found it dated and lacking in substance.

Although Marilyn Monroe stars in the film, much of her role was completed by her stand-in and body double, Barbara Luna, due to Monroe's declining health and addiction issues during production. Monroe's scenes were filmed in a limited schedule, and she passed away before the film's release.
