Totally Maz, both DP and I are almost certainly somewhere on the spectrum. All the things Lu said, I experience too. Food issues (mostly texture related), sensory issues - mostly auditory but also tactile, spacing out in conversations, a tendency to dominate a conversation or be slightly obsessive in subject matter, insane memory for trivia, and numbers, a visual memory. It wasn't until DS was diagnosed that I really started to identify those traits are being typical spectrum traits though. I have often felt that a much larger percentage of people are on the spectrum than are ever tested, but because their traits do not manifest in a way that causes them distress or difficulty then testing (or intervention) is never required. Even though DS' spectrum traits are difficult for him (and for us) to manage, they also make him the clever, creative, wonderfully unique little oddball that he is. And as DP and I are both clever, creative, wonderfully unique oddballs ourselves, he fits in pretty well around here LOL.

It's made me wonder though, if the combination of DP and my genes has had an exponential result on DS (ie: he's much more severely affected than we are to an extent that he's unable to self-manage without intervention), or whether the lack of both diagnostic and treatment tools when we were growing up meant that we self-managed because there was no other option.
