33% of Fetishes Have to Do with a Specific Body Part
A 2007 study from Nature used Internet discussion groups to estimate the prevalence of fetishes in approximately 5,000 people. They found that preferences for certain body parts (like body weight or feet) were the most common type of fetish, with this accounting for 33 percent of the fetishes. Objects usually associated with the body (like headphones or shoes) came in second with 30 percent. Foot fetishes and fetishes relating to objects associated with the feet were the most common.
