I too am quite secretive (and on the spectrum). However, I view it as a protectionist measure, rather than a choice. Growing up I became accustom to getting picked on if I shared anything, so now I just don't share anything. It's unfortunate to say that there are things I don't even share with my partner. Trust me, I want to, but I just can't bring myself to for a number of reasons.
So whilst I don't know whether it's a trait as such, I do think that it's common as a protectionist measure.
I feel the same way.
But it is a choice we have taken, as a protectionist measure - even though I would rather like to be able to share without getting picked on in return. That's just not how it works.
