Warning: some of these "philias" are NSFNFS (Not Suitable For Nightmare-Free Sleep).
Via one of our favorite sources comes a fun illustrated diagram [1] featuring fetishes such as microphilia, an attraction to little people, and 24 other extraordinarily creepy sexual proclivities.
Here are a few of the fetishes, along with examples of those afflicted with these preferences:
Tricophilia: arousal from hair. eg. a yeti's girlfriend, the guy who rescued Rapunzel.
Hybristophilia: arousal to people who have committed crimes. eg. Bonnie, Clyde, pen pals who marry incarcerated murderers.
Retifism: arousal from shoes. eg. Half of the world's population.
Abasiophilia: attraction to people with leg braces. eg. Er, Jenny from Forrest Gump?
Now, we know that what floats one person's sexual boat can equate to a quickly sinking libido for others. Talking dirty [2] can take some getting used to if it isn't your go-to, for example. It's the dachryphiliacs, those attracted to making one cry, and emetophiliacs, those attracted to vomit, who might have a tougher time working out their differences with their partners.
According to one fetish poll [3], masochism seems to be the top ranking "alternative" sexual predilection [4], followed closely by odaxelagnia (biting) and xenophilia (attraction to foreigners), all of which are leaps and bounds more manageable than, say, coprophilia [5].
