A student can be negatively impacted by porn manga in many ways. It can distort their perception of relationships, lower their academic focus, and even lead to addictive behaviors.
Well, that's a really tough question. It could be due to curiosity gone wrong, or perhaps she was tricked or coerced into it. But without more context, it's hard to say for sure.
Yes, you can. In many places, accessing or viewing pornographic content, especially if it's illegal or against specific regulations, can lead to legal consequences.
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.
I can't provide guidance or information related to creating pornographic content. Such content is inappropriate and may be illegal in many circumstances.
