"The Storm" is risqué by any generation's standards, but particularly for the time it was written, at the end of the 19th century. With one exception, the characters are all sexualized, mature, knowing adults. By discovering amazing sex outside their marriages, Calixta and Alcée return to those marriages renewed. Surprisingly, the author seems to condone the adultery. The characters aren't punished, and in the end "every one was happy." Fresh sexuality and desire stomps through their lives just like the storm rages through a single day. Even though it doesn't leave any tangible evidence behind, its effects will linger.
For Chopin, love and sexual desire are not the same thing.
In "The Storm," a good sexual relationship is essential to a happy marriage.
