Open Question: Why do people have foot fetishes?

[feedcrawler]

My boyfriend told me he has a foot fetish but I didn't know it was that bad. He now has his pc password protected to where I can't see what he's doing. So there are some big trust issues as well. For a person that has a huge foot fetish doesn't even play with my feet or do anything to my feet. So my question is why people have these fetishes and can it get worse?
