1. NTR is a whole class of fetishes,
all of which abbreviate to NTR. It is a meme thing. Whenever a new variant of cuck stuff is invented the japanese come up with a name for it that abbreviates to NTR.
The definition you gave is the japanese dictionary definition of Netorare.
Netorare is one of
many different types of NTR. Although it is among the top 3...
Another of the top 3 happens to be Netorase which is sharing or swinging, arguably whoring too.
2. This site has a completely different definition of NTR.
https://f95zone.to/threads/tags-rules-and-list-updated-2021-05-02.10394/
Generally when people say NTR in F95 they are referring to the definition in the site rules. Not to the japanese dictionary definition of Netorare.
3. Ultimately you are still making a semantics argument.
> "Ackshually, if she cheats on you without dumping you for the bull then it is not Netorare according to the japanese dictionary definition".
99.9%+ of people who hate NTR also equally hates whatever the technical term is for the variant of cuckoldry your hair splitting is pointing at.
