Inasmuch as the word
fetish has deviated from its original meaning (that being a part of the
anatomy imbued with
magical powers, especially in the realm of the
unnecessarily sexy) to apply to such distinctly extra-bodily (that is, originating from outside the body, not necessarily not entering it) items as
PVC,
ball gags,
whipped cream or
poodles, the domain of mystical, enigmatic or uncanny attractions to specific
body parts has been moved to the realm of
partialism.
Repeat after me: I have a castanet fetish; I am an elbow partialist.
I have a tootsie pop fetish; I am a navel partialist.
I have a pinecone fetish; I am a uvula partialist.
Very good.
