Is it normal to have a helmet fetish

I actually enjoy men with motorcycle helmets on and looked it up to see if it was normal and found this. I had to look it up because not only do I like them with the helmet on but I feel like it ruins everything for me when they take it off at all it's a really weird dissatisfied disappointing experience when it's removed or esp if I see their face beforehand. And I've had this fetish since I was probably 13 so I guess we must be normal in a different manner :)
