No. Due to their often inappropriate nature, they are not considered a mainstream or popular genre in literature. Most readers prefer more positive, educational or at least family - friendly genres.
Alien erotica is not a genre that is widely promoted or considered appropriate in most literary circles. It often contains content that may not be suitable for general audiences. Instead, you could focus on regular science - fiction short stories about aliens which can be found in many anthologies.
Classic science - fiction adventure stories are a great alternative. For instance, the 'Star Trek' related short stories that focus on exploration, discovery, and the relationships among the crew members. These stories are full of excitement and positive values.
Reading such content is often not considered mainstream or appropriate in many contexts. However, if you are interested in science - fiction stories with alien themes (without the erotica aspect), you can check out well - known science - fiction bookstores, both physical and online ones like Amazon. They have a wide range of science - fiction short story collections.
The theme of adaptation also frequently appears. The human characters usually have to adapt to the alien environment, which includes getting used to the alien's way of life, social norms, and of course, their sexual mores. This can lead to some interesting plot developments as the characters navigate their new and often very different world while also dealing with their growing feelings for the alien characters.
Another one might be 'Zerconian Warriors' series. It features interactions between humans and alien species in a sci - fi setting that also includes some romantic and sensual undertones. The books explore the relationships that develop between the different species.
Classic fairy tales can be a good substitute too. Tales like 'Cinderella' and 'Snow White' have been loved for generations. They often carry moral lessons and are full of charming characters and magical elements.
