I'm not sure specifically which 'gay Apollo story' you are referring to. There could be various fictional or less - known interpretations related to Apollo in a context that might involve homosexuality. Without more context, it's difficult to give a detailed account.
It's not a well - known myth at all. Greek mythology has a vast body of stories that have been passed down through the ages, and the mainstream ones don't include a 'gay Apollo story'. However, in some contemporary or alternative interpretations, there might be such a story, but it's not part of the commonly - known mythological heritage.
There are many interpretations of Apollo in mythology that could be related to same - sex relationships in a sense. For example, Apollo's deep friendship with Hyacinthus. Apollo was so fond of Hyacinthus that when Hyacinthus died accidentally during a discus - throwing game with Apollo, Apollo was heartbroken. He transformed Hyacinthus into a flower. This relationship, while not explicitly 'gay' in the modern sense, shows a deep emotional bond between two male figures in Greek mythology.
Some gay Apollo fanfics also deal with the concept of immortality. Since Apollo is an immortal god, when he has a relationship with a mortal, the theme of the mortal's mortality and how it affects their relationship comes into play. It could be about the fear of losing the mortal, or the different perspectives on life and time that the immortal and mortal characters have.
Another way is to join relevant fan communities. There could be groups on social media platforms like Facebook or Reddit that are focused on Greek mythology fanfic, and specifically on Apollo. Members of these groups might be able to recommend good Apollo gay fanfic or even share their own works.
There are fanfics that might reimagine Apollo's love life in a way that delves deep into his character traits. Maybe a story where he falls in love with a mortal man and has to deal with the complications of their different existences. In these fanfics, the author can play with the themes of love, sacrifice, and the clash between the divine and the mortal worlds. It could be a really interesting read as it gives a new perspective on the well - known deity.
Apollo 18 isn't real. It was created for entertainment purposes and doesn't represent actual events. The story was made up to thrill and engage the audience.
