Is it normal i love rubbing my feet on things?

I'm a straight man, I have a foot fetish but mostly for my own feet. Since I only have two hands and can't comfortably massage my own feet while operating a computer, I instead just enjoy rubbing my feet on things. Whatever is nearby, or just on each other. For me, the contact makes them feel really good for a few seconds before it fades and I go back to what I was doing.

Anyone else enjoy doing this from time to time?
