It depends. In some contexts, they can be considered inappropriate as they may contain explicit sexual content that goes against certain moral and social norms. However, in the realm of adult or erotica literature, they have their own readership. But overall, in mainstream and general literature aimed at a wide audience, they are not appropriate.
Well, sexual erotic stories are generally not appropriate in most forms of literature. Mainstream literature is expected to uphold certain values and ethics. These types of stories often focus too much on sexual aspects which can make many readers uncomfortable. They also may not contribute much in terms of positive literary value such as deep character development or exploration of important social issues. So, in general, they don't fit well in the broader literary landscape.
In general, sexual erotic stories are not appropriate in mainstream modern literature. Literature is often a medium for expressing a wide range of human experiences, emotions, and ideas. While sex is a part of human life, presenting it in an overly erotic way can overshadow other important elements. Moreover, it can be offensive to some readers, especially those who are more conservative or those who expect literature to be more about intellectual and emotional exploration rather than sexual titillation. However, in some niche areas like erotica, they are designed specifically for an adult audience with a particular interest in that kind of content.
