Fear of germs, is this OCD?

I'm not sure if what I have is OCD or not. I'm afraid of germs. I can't use anyone else's cups, plates, forks, knives, or spoons unless they're the disposable kind. I can't drink or eat after anyone. I can't eat unless my hands are washed. However, I'm fine eating fast food and at restaurants, though I know they must be a lot dirtier than someone's house. I just can't help it. I also can't sleep in another's person's bed or sheets because it grosses me out thinking about the last time they washed them or the germs on them. Is this any type of OCD or just me being irrational?
