I suspect I have mild OCD. I suppressed it since my mother got nervous when I was little and she saw me lining up stacks of magazines on the coffee table. It is definitely the kind of thing you can overcome. It did pop up again later when I would find myself turning off the oven dials at night, all the way, one by one. I made myself stop doing it.
The funny thing was, at a fundraiser, this woman whom I would NEVER have suspected of having OCD told me that she did, and when I told her about the oven dials, she said, "YES!" with genuine, unfeigned recognition. It's funny how you can have unexpected things in common with someone.
A guy on Twitter even has it, tweeting photos of his immaculate home and saying he cleaned it because he has OCD. Unfortunately, I don't have that kind of OCD. I try to sweep if there is food on the floor, but it's only because I don't want bugs.
