I noticed ( if I'm wrong, then correct me) that the most women with pregnancy fetish that I noticed are ebony women (I once talked to one I would be in Paradise, supposedly she wanted to be pregnant with me so that we would start having sex throughout the pregnancy, so much that a huge distance canceled the plan), Latinos and Asian, probably mainly through hentai, are Japanese. White women are mostly American women. In Europe, there is a terrible lack of this I see and better, even on the forums to stay away from it

Correlation based on existing data doesn't mean causation; doesn't mean that some nationalities of the pregnant women have been more frequently represented with a pregnancy fetish doesn't mean that such nationalities are more predisposed to develop the kink.

Maisiophilia is a sexual paraphilia that will require further study from the appropriate bodies of knowledge (mostly psychology and other social sciences) to determine more accurately what kinds of populations are susceptible to developing it and from what I know, paraphilias are a form of deviancy in the criteria in what defines a mental disorder (or what's called as paraphilia-related disorders) and can only be addressed as such if the person having it has had their personal lives affected detrimentally and the lives of other people that interacted with such person have been harmed or worse, killed, but I digress.
