That's crazy that the basis for your take on Japan being a "cuck nation" is "i think". You don't have any evidence suggesting it is, I'm sure there are no studies done on it, so you are just assuming based on the porn or other content that's available online.You do realise that every fetish has a point of inception? For example if you see a country or a culture having more pronounced one fetish than the other it means that there are some social-engineering things at play. Not saying that someone tries to make every S/M fan or Cuckolding fan, i'm trying to say that some things that are happening in our life/society are pushing you towards specific fetish.
Normally it's localized and there aren't much fetishes at all or they are somewhat distributed without much pronunciation.
Japan is a cuck nation (not really the main fetish but out of all countries Japan i think is #1 in cuckolding fetishsm).
This is due to their culture and their social rules that are perfect breeding grounds for that fetishism.
Now my question is what changed in western world that cuckolding fetishsm is on the rise? If you think it's natural, i envy your ignorance and bliss from enjoying without brooding over it.
I analyzed my fetishes, and every one of them had point of inception that started me on this path. What i don't know, is what was the cultural catalyst for the cuckolding fetish in western countries began to rise up.
Why are western men becoming submissive and/or prone to seeking pleasure from coping mechanism. (NTR gives you pain but at the same time it gives pleasure as a coping mechanism).
Almost every fetish inception point is known to psychology (reasons for it happening). What is interesting is when it happens en-masse and what cultural triggers made it happen.
Cuckolding have been a thing for a while, you can trace it back to even roman times where they were a lot more secure with their fetishes than today. There's evidence of cultures that used to share their women with travelers. You can look all this up. I had an uncle who lived with his wife and another male in the same house, and we knew the kids were not his, but no one in the family said anything because it's their life (this happened in the west btw). Look up rumors of slave owners who practiced cuckolding and the mixed children they left behind in the south. Cuckolding is not a new thing, you're trying to find a pattern or theorize something and find a trend when you need to realize that we are more connected through the internet than ever. Most these fetishes used to be shared among like minded people that happen to live in a small area code, now through the internet we are able to find other like minded people and form our own communities. just look up where the world cuckold is trending the most in google trends since 2004 and it's Myanmar, not even the west. But to be honest the word is different in each language so it's probably a different country.
There is no propaganda here, or a secret mission to corrupt the west. You're trying to form a theory that doesn't exist. I believe the rise in these searches and content are because people are getting more comfortable with themselves and find it no longer necessary to hide it from society since they can share these things over the internet. I gurantee that if you go outside you will not see couples with a third partner or if you travel to Japan you will realize that cheating is not the norm or NTR or whatever is not the norm. Don't let things online affect your judgement, the world is a big place we just find like minded people easily online now than before.
