I've always been very much the same, it's not quite as all encompassing for me as it once was, I've managed to train myself out of most of my OCD habits, mainly due to being around people who used it as an opportunity to wind me up.
Many years ago, shortly after my wife and I started courting, I had a huge DVD collection (a few thousand titles) that I kept on a sizeable bookcase, organized into genre, series, alphabetised etc. Above all else though, every DVD case was precisely flush with the edges of the bookcase.
For some reason, she found it very amusing to poke a few cases slightly further onto the shelves or pull a few out just a little, and within seconds of me entering the room I'd spot it. It got to the point where I'd be waking up at 4am and checking each and every DVD case just in case.
Bloody neurotypicals eh!
