Avoiding themes that are too narrow and focused only on sexual aspects. Instead, incorporate more universal themes like friendship, family, dreams, and personal growth. This way, the novel can resonate with more people who are interested in different aspects of human experience rather than just the sexual aspect.
Also, overly vulgar language should not be used. Using refined and respectful language can make the novel more accessible and appealing to a broader range of readers. For example, instead of using crude words to describe emotions or situations, use more elegant and nuanced expressions.
Definitely, any explicit sexual content should be avoided. A wider audience includes people of different ages and backgrounds, and such content is not appropriate for general consumption.
