Does liking this mean something's wrong with me?

I have been carrying this around for years and I have never asked anyone, so apologies if this is the same question everyone new asks.

I like feet. That has been true since I was quite young. Nothing about it has ever involved anyone who did not want to be involved, and it has never caused a problem in any relationship I have had. But I still have a low level worry that it points to something, like it is a symptom of something in my head that I should be dealing with.

I have read the sort of thing you find when you search this at midnight, which was not helpful in either direction. What I would rather have is a straight answer from people who have thought about it for longer than I have. Is this the kind of thing that means something, or is it just a preference?
