You got it all wrong. West is all about cuckoldry since the ancient times and then it got exported to the different continents (probably the first thing they did). I mean, it's true. Only recently ntr became popular in Asia (after western invasion yes). It's all about money actually, so when prostitution is a popular hobby, ntr inevitably is going to be a thing. This also explains why people hate ntr (generational childhood trauma).West it isn't like that
