The differences between 'a' and 'x' porn comics can be quite diverse. It could be the way the characters are portrayed, the quality of the illustrations, or the themes explored. Sometimes, one might have a more unique approach to sexual content than the other.
The main difference might be in the characters or scenarios presented. 'A vs X' comic porn could have specific character conflicts or unique storylines that set it apart from the usual.
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.
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.
