You are not alone mate. I have OCD and have my little fetishes. When I post I attempt to keep it short if possible as I check and recheck over and over again. This is the main reason I edit a fair bit on my posts as I keep checking even after posting.
It's mainly poor grammar and spelling "I'm after" and I feel compelled to achieve this perfection at all costs (In my eye's) if I'm having a "OCD day".
We all have our little "thingies" I guess.
I won't check this post as a bit of a behavioural therapy exercise.
All the best
