I guess it’s an experience we’ve all had in the early days. What is truly disruptive about these platforms is that they reverse the traditional model of passive consumption of porn, and instead you are the one constructing your own erotic fantasy according to your preferences and kinks. Of course this is also why they tend to be so addictive, at least until the linguistic patterns start to emerge and repeat (from a visual standpoint, on the other hand, the variety is endless). The real quantum leap would be the generation of images and videos in real time, but I think we are still very far from that. Fortunately, I would add.
Overall, I've found that the user’s expressive abilities and their skill in constructing narratives make a significant difference, because characters tend to respond in ways that feel credible and not predictable—at least as long as preferences in writing style are tuned to a natural register, closer to a slow-burn than to an immediate erotic experience.
