Then, why did you wonder if you have yellow fever? Clearly you don't. Besides, anybody who cares about other people's personal aesthetic preferences probably is insecure. Usually it's rich spoiled Asian-western girls who don't have any feeling of connection to their ancestral culture or their living country's culture, because in youth they rejected their heritage and as adults regret it. Or, some girls obsessed with American culture and buy the idea of America as perfect and worth imitating. In either case, their use of "yellow fever" doesn't have real meaning, it's only a way to reject guys they don't like without taking personal responsibility for rejection. They even say it about Asian guys if their perception is that he isn't "really Asian" somehow, such as he has a neutral accent in English or other ridiculously shallow reasons. What such girls have is "yellow fever Truman show delusion" because they perceive other people as "fake" and as if the world revolves around them and being Asian. Their effect on insecure men is "Munchausen's yellow fever by proxy" because they convince healthy men that they're sick, that they have this disease they really don't have. Because girls like this define "yellow fever" in most people's consciousness, it isn't how it originally was used and lacks all the worthwhile considerations that used to be the reason why the term even exists.
In the context of JAV, it really doesn't make any sense to think of "yellow fever" if you value JAV as unique Japanese porn. If you don't, so if you only watch JAV because you're opposed to American porn and amateur videos from other countries are not enough, maybe then it's a possibility but "yellow fever" is a disease with a cure. JAV can be this cure, so even somebody who really has it could be cured by JAV if he begins to conceptualise the unique Japanese phenotypes and aspects of Japanese culture such as the Japanese language or architecture among other reasons, through JAV. In this way, his genuine yellow fever could be cured. For you this doesn't sound like the case, however, some other posters could be. Really it's important to remember that nobody is immune from being infected with yellow fever because it is a real disease, a serious mental illness, though with extreme amounts of misinformation and also misunderstanding that make it difficult to assess. Even somebody who was born and raised and lives in as an example Japan could be infected if the seed germinates. This is why it's important to differentiate yellow fever from preferences. Sadly many people can't do this, and the result makes increasing men into self-hating and repressing their sexuality that even turns into Munchausen's yellow fever by proxy because of girls with yellow fever Truman show delusion.
If your only concern is lack of fat and tattoos, it sounds like a simple aesthetic preference. This could be political too. However, in any case it is not yellow fever. An example of yellow fever is if a man (this even could be a Japanese man) is convinced that really all Asians are the same and he only cares about sticking his chinpo in any Asian girl even if she's ugly because he is unable to conceptualise her as ugly as a result of facial blindness, and the litmus test is if he reacts negative against her having a connection with a specific culture. If you want to read about this in off-topic depth, search about Japanese soldiers during WW2 and some interpretations of the GEACPS. Of course the term "yellow fever" is not used in this context but, compare and you'll see for some it was the same.
When we're talking about JAV, the consideration of aesthetics can focus on phenotypes as we discuss on /jav/ but it also includes what you said, body types and tattoos and such. From the very large amount of JAV actresses, we all can find some we like. Fat true hag with tattoos and piercings? Yes, even she exists! Regarding fetishes, JAV really has more variety than even American porn. It's the perfect porn. Somebody who has yellow fever wouldn't appreciate any of this how we do. For me, because I like all kinds of types and fetishes, the variety of JAV already has most available and in cases where it doesn't, then some other porn usually does. Not everybody has to be a varietychad and it even can be interesting to hear the perspectives of people with very specific exclusive niche tastes, but I fkn enjoy the ability to discuss all JAV on /jav/ and the autism.
Do any actresses you still like after Kimming as much as before exist, or is it always in every mood some preference for the natural forms? Which JAV actress is the "fattest" you still like, by your own definition of what it means to be fat and how far you still enjoy? About tattoos, is it even if it's hidden but you know she has one or is it only about if you see it?
