It can be appropriate in a literary context if the story has significant literary merit. A sex story could be used to delve into deep psychological aspects of characters, like their desires, inhibitions, and how society's views on sex affect them. But one has to be cautious. The language used should not be vulgar just for the sake of being vulgar. If it is part of a greater narrative about love, self - discovery, or cultural exploration, then it might find a place in certain literary circles.
In a literary context, submitting a sex story can be a complex matter. If it is done in a tasteful and purposeful way, such as exploring themes of human relationships, sexuality as a part of character development, and is presented with high - quality writing, it can be appropriate. However, it also depends on the target audience and the platform. For example, in some literary magazines that focus on adult - themed literature, it might be acceptable. But in more general or family - oriented literary spaces, it would not be appropriate.
