I'm thinking that you are asking a serious question about something that bothers you. So, I'll try, from my experience in mental health to give a serious answer:

Who the heck cares????

No, I don't mean who cares about YOU -- but who cares about the counting?

Even in the DSM (the bible of mental diagnostics in the US) nearly every condition they describe is qualified where the symptoms of the disease must cause some kind of serious problem: that the symptoms of the disease impair your ability to work or function in society...

And, even in those people with very severe mental illness, the goal is not to cure the disease (which can almost never be done anyway) but to manage it so the person has a higher quality of life. A wonderful example of that is "The Aviator" about Howard Hughes who had severe OCD -- but he managed to manage it and, by most people's standards lived a very productive life (until he let it get out of control).

So, if it doesn't hurt anything and if you enjoy doing it (or feel less uncomfortable doing it), it probably is not a question worth asking...

But, since you brought it up: Based on what you said, I seriously doubt that you have OCD. A therapist would go into a lot more depth and detail, but from the little you have told us, it probably doesn't qualify as OCD...

But, speaking of counting: we lost a great one a couple weeks ago: The Count von Count of Sesame St passed away...
... Now HE was somebody you could count on!
(sorry)
