No. These types of stories often involve complex and potentially confusing concepts about gender roles that are not suitable for young children. Children at a young age need simple and positive stories that help them develop a healthy self - image.
One common theme could be the exploration of gender roles. It might show how a young boy experiences a different set of social expectations when put in a situation related to 'petticoating'. Another theme could be the boy's self - discovery during such an experience, like understanding his own identity in a new context.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
The main distinction of porn with a story genre from regular porn is the presence of a coherent narrative. Regular porn often jumps straight to the sexual action, while the story genre tries to add some kind of story framework around it. But in the end, both are adult-oriented and feature explicit sexual content.
