What OCD is really like

I have OCD. I'm not not just saying that because I prefer things to be a certain way or super clean. I am not self diagnosed, I was diagnoses by 3 medical professionals, and have been on medication for it for a year. When I was doing some reading today, I was reminded yet again how misunderstood OCD actually is. There is a lot that people don't tell you about, and some of what they do tell you is wrong. I want to help set the record straight. Ask me ANY questions you like about OCD, no matter how obvious, stupid, silly, whatever. I will do my best to answer them. Although, I may say at some points that I don't entirely know the answer, because obviously I don't know everything (as nice as that would be), but I will say that in the answer. I don't want to spread more misconceptions :)
I don't expect to get 500 questions in a day, so it doesn't matter when this was posted, even if it was two years ago, you can still ask :)

Sorry if this seemed like a rant, It was not meant like that :)
