ebo.ericsson My understanding is that the correct term for navel fetishism specifically is "umbiliphilia," whereas "alvinolagnia" has more to do with the belly itself. There are articles for each in Wikipedia, each saying that one often coexists with the other (e.g. many navel fetishists are at least somewhat attracted to the rest of the belly, and many belly fetishists are at least somewhat attracted to the navel). https://en.wikipedia.org/wiki/Navel_fetishism https://en.wikipedia.org/wiki/Alvinolagnia http://www.bellyinc.com/bellyforum/index.php?topic=3801.0
