Sure. One great family - friendly story is 'The Polar Express'. It's about a boy who takes a magical train ride to the North Pole on Christmas Eve. Another is 'Rudolph the Red - Nosed Reindeer', which tells the story of Rudolph's journey from being an outcast to a hero on Christmas.
However, in some works of literature that deal with complex human nature and social problems, sexual content may be mentioned in a more euphemistic and meaningful way to serve the overall theme, but this is very different from extreme and inappropriate sex stories. For example, in some novels that explore the dark side of society, a bit of sexual description might be used to show the decadence of a certain environment, but it is always within the framework of art and morality.
Think of an uncle who was an artist. He would let his young relatives come to his studio. He taught them how to draw simple things like trees and animals. He also told them stories about famous artists and how they created their masterpieces. It was both educational and fun for the kids.
In modern literature, the presence of dirty sex stories is a controversial topic. On one hand, some may argue that they are inappropriate as they can be seen as vulgar and violate moral and ethical norms. However, others might say that if they are used in a context to explore complex human relationships, sexuality in a psychological or sociological sense, they could have some merit, but they should be presented with great caution and within certain boundaries.
In a civilized society, we should uphold good moral and ethical standards. These types of stories are not in line with the values that a healthy society tries to promote, such as respect, equality and propriety.
