I collect/really like shoes and I've heard people say things like, "I have a shoe fetish". To me, that doesn't mean you're just a fan of shoes. It conjures up visions of someone who might break into your house, steal your shoes and do stuff with them that might make you never want to wear them again.
However, I would have to agree with Nautilus in that if you're married and you want to wear a gummybear in your belly button and have your spouse call you King/Queen Bombula of the Gummy Tribe, I don't feel the need to judge you. But I don't want to hear all about it or see the pics on Facebook either.
