Is my relationship actually unique?

I see all these questions regarding arguments, unsatisfactory sex, mind games, etc. I have none of that in my relationship. We've never had a fight, only a few mild disagreements that were resolved without either of us getting angry or using raised voices. Our sex is great. The only time there's anything resembling mind games or weird behavior is due to miscommunication (we have learning disabilities so we sometimes don't understand all social constructs). So is my relationship really that special and unique? Do people with a similar relationship just not lurk here (I do, but it's for a different reason)?
