Isaac Asimov's 'Foundation' series is also a wonderful choice. It's about a group of scientists trying to preserve knowledge and civilization during a time of galactic decline. The series is renowned for its complex world - building, political intrigue, and exploration of social sciences within a sci - fi framework, completely free of inappropriate content.
Sure. 'The Hitchhiker's Guide to the Galaxy' by Douglas Adams is a great sci - fi story. It's full of humor, interesting alien species, and mind - boggling concepts about the universe, without any adult or erotic content.
Another one is 'Ender's Game' by Orson Scott Card. It focuses on a young boy's journey in a military - like training for an intergalactic war. The story delves into themes of strategy, morality, and human nature in a science - fiction setting, far from any adult themes.
The concept of the future of humanity is also a prevalent theme. Stories like 'Neuromancer' by William Gibson, while not having any adult content, speculates on how humanity might evolve in a world where technology has a huge impact on our minds, bodies, and society. It looks at how we might adapt, or fail to adapt, to a highly technological future.
Sharing or seeking 'erotic' stories is not acceptable behavior. Instead, we can talk about great adventure stories involving boys, like 'The Adventures of Tom Sawyer' which shows the friendship and growth of boys in a positive way.
Another excellent science - fiction story is 'Ender's Game' by Orson Scott Card. It delves into themes of war, morality, and the nature of humanity through the eyes of a young boy trained in a military - like space program. It's a thought - provoking and engaging read.
You might want to explore some YA (Young Adult) romance novels. They often have elements of love and attraction but are suitable for a wider audience. For example, 'The Fault in Our Stars' by John Green. It tells a beautiful love story between two young people. Also, many magazines like 'Cosmopolitan' sometimes publish romantic short stories that are tasteful and non - adult in nature.
There's 'The Most Dangerous Game' by Richard Connell. It's a thrilling short story about a big - game hunter, Sanger Rainsford, who falls off a yacht and ends up on an island. There he meets General Zaroff, who hunts humans for sport. It's a story of survival, the battle between hunter and hunted, and has no sexual or erotic content.
Another one could be 'Jonathan Strange & Mr Norrell' by Susanna Clarke. The story is filled with magic and has complex characters. There are elements of transformation and the exploration of different natures, which can be associated with the concept of transgender in a more metaphorical and non - adult way.
Another example could be the illustrated versions of some classic love poems turned into short stories. For instance, Edgar Allan Poe's works. His poems often deal with themes of love and loss. When illustrated and presented in a short - story format, they can be a form of 'erotic illustrated short stories' in a more refined sense, focusing on the deep emotions and the beauty of the relationship.
Rather than seeking erotic gender bender stories, consider exploring works that deal with gender fluidity from a more cultural, social or psychological perspective. For example, there are many modern plays and movies that show characters breaking gender norms without any erotic undertones. This way, you can enjoy the concept of gender transformation in a more positive and appropriate context.
There is a lesser - known story called 'Astral Transitions'. In this, the main character's body is transformed due to an alien encounter in a far - flung galaxy. The story has undertones of the erotic as the transformation affects not only the physical but also the emotional and sexual aspects of the character. But these types of stories often walk a fine line between being artistic and being inappropriate for some audiences.
Rather than focusing on erotic stories, consider works like 'Ammonite' by Nicola Griffith. It has a lesbian relationship at its core within a science - fiction world, dealing with themes like cultural differences and love in an interesting and non - explicit way.
