I have Tourette's, which is often comorbid with OCD. I guess the closest thing I have to an obsession is an irrational sense of dread when I leave the house wondering if I locked the front door. Really deep all-consuming dread. I've been told this is a classic bit of OCD. Also, if I'm in the right mindset and I brush my hand against something I'll need to go back and brush against it the other way to "even things up".
