I've shared my experiences with various SO's elsewhere with my openness about my CDing. I live a very open life when it comes to my SO, I can't be very genuine unless I do. There are very few secrets or things I wouldn't tell her. The result of this is we have a very deep and intimate relationship. We are open to each other.
That said sometimes you keep things a little closer to the chest. If we are having a difficult time (not necessarily in our relationship but maybe something like the death of a close relative), I sometimes won't say things in order not to make things seem worse. I tend to be an optimist so often it's just keeping a stiff upper lip to get through a situation. Not because I'm not willing to share but the timing isn't the best and it doesn't help to keep focusing on a negative situation.
