Since I'm not entirely sure what an 'asstr model' in sex stories really is, it's difficult to say if there are different types. But if it is a model for characters or scenarios, then it's possible that there could be different types depending on the variety of sexual situations and characters depicted in the stories.
If we assume that 'asstr model' is related to the structuring or categorization of elements within sex stories, then yes, there could be different types. It could be based on different sexual orientations, for example, a heterosexual 'asstr model' and a homosexual 'asstr model' in the context of how the stories are constructed and the relationships are portrayed. Or it could be different based on the emotional intensity of the sexual encounters in the stories, like a passionate 'asstr model' vs. a more casual 'asstr model'.
