A goofy plot in a porn comic might involve funny misunderstandings, over-the-top scenarios, or characters with comically exaggerated traits. It's all about adding a humorous twist to the otherwise adult content.
A goofy plot porn comic might catch attention if it offers a new perspective on sexual themes or if the art style is distinct and complements the odd plot.
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.
