Thanks! I tried to be fair, but I am worried that either my message was not clear, or that some people replying just didn't watch the video.
As I already mentioned in my previous post you put some reasonable thoughts into your research and this is why I want to give you my full feedback on it.
Please keep in mind that I'm not an English native speaker and that I might sound rude or offensive, but that's not my intention, because same as you I think NTR is an interesting topic that needs to be discussed with an open mind and in polite way.
You try to shed light on the popularity of NTR by backing your argumentation from psychological, sociological, and paleo-anthropological angles and the research that had been made in those fields. While you were able to show why people fantasy about certain scenarios and their reasons behind it, your analysis fail to show the link between a taboo fantasy and its rise in popularity. There are no information provided from your side that shows that there is a potential positive correlation between a taboo fantasy and its rise in popularity. The question: Why is NTR is so popular remains unanswered based on your argumentation.
Now we know that people fantasies about taboo topic and that they never want that to happen to them in real life, but did that lead to a rise in NTR's popularity? Have sales for NTR content increase over that last 10, 15, 20 years? Do more and more artist implant or even switch completely to NTR content in their projects?
Some numbers would be nice that could go hand in hand with your argumentation, showing if popularity of NTR went up or down, or even stagnated over the past few years.
While your scientific search looks impressive on the first glance, it doesn't shed light on the initial question. I could simply switch the question to: "Why is loli content so popular?" And use the same scientific research to back my argumentation. "It's a fantasy; it's a taboo topic; no one would do it in real life; shadowplaying to overcome a trauma; etc."
Would I judge purely on your video I would say you didn't understand what NTR (netorare) is about and that you only scrapped on the surface of it.
Because you didn't make a distinction about the scope of your research field I don't know if you meant that NTR's popularity in general (including Japanese porn videos, Hentai manga/anime) or only in adult games is on the rise.
Even then, you would need to define what "NTR" (netorare) is. From Xando's link you could get a first idea of how vast and complex the whole NTR debate is. Different people have different definition about NTR and what they think it included.
Here is an example of the amount of threads on this subject. (It's not all of them).

If we limit the question about NTR's popularity to F95, then the answer would be easy. NTR's popularity is on the rise due to the buzz it cause. And by that I only mean the word "NTR" and not the game/comic behind it.
The social and psychological impact of NTR is an interesting aspect in my opinion, because if you look into Japanese's society (same goes for China and South Korea) you will come across the "social face".
A person that lose their public/social face is a failure of society, an outcast with no honor. NTR builds on this emotional breakdown to maximize its impact on the consumer. Therefor, it might be possible that non-Japanese/Chinese/Korean can't really understand and comprehend the sheer emotional impact of NTR.
There are a lot of things that need to considered when it comes to NTR, which can't be easily narrowed down to: "it's a taboo and people fantasies about it".
However, thanks again for your video and research on NTR and hopefully my feedback didn't scare you away from the topic.
Take care.
