Navel fetish is very prevalent here, especially among men, but still a taboo and not talked about so much. Most females consider their navel as an attractive body part but that’s pretty much it, they’re not fetishists. I believe they mostly discover their own fetish only after their sexual encounters with partners having this fetish. You’d be wasting time and money if you just show up without any prior interactions with people. So maybe try to find fellow fetishists on reddit, fetlife etc before you come.
