I decide based on how much it will effect the person I'm dealing with and how much I trust them.

I don't always talk about it directly in my personal LJ. I don't use filters, as I'm not particularly fond of them.

My advice is to ask yourself why you feel they should know about any aspect of your life including that one, and weigh that against what risks you might be taking in telling them. Figure out what your priorities are, and create a game plan that will allow for them.
