To begin writing erotic fiction, you have to be comfortable with the subject matter. Read some examples from well - known authors in the genre, not to copy but to understand the style. Think about the settings, like a secluded beach or a luxurious bedroom. Build the sexual tension gradually in your story. But always keep in mind that there are certain moral and legal limits to this kind of writing. For example, it should not involve non - consensual situations or promote harmful behaviors.
Well, starting to write erotic fiction is not much different from other types of fiction in some ways. You should start with an interesting premise. Maybe it's about a forbidden love. Develop the characters' personalities and desires. However, it's important to note that such content should not be offensive or violate any laws.
