Personally, I don't. Mostly from privacy concerns. I followed the same path that many others, I notice. Very paniced when I first joined, posted anything and everything followed by an OMG! what if she reads this!, an attempt to cover my tracks and undo what I wrote.
After establishing myself here and was accepted into the private area, I found that to be a perfect place to let it all hang out, so to speak.
Additionally, I feel that it is not my secret to share. Meaning that it is not my place to decide to publicly reveal what happened. If my wife wants someone to be aware, it's something that she will do. That took a while for me to realize. So I speak in general terms in public areas and more specifics when I am assured of privacy.
