To those of you that have had horrible repercussions from being outed, my heart goes out to you. I hope it only makes you stronger in the end.
The only person that "officially" knows is my wife. A bunch of friends have seen me dressed on two different Halloweens, but they all thought it was just a costume and that was it.
If my friends have seen my flickr page, which I show my face and I'm fully dressed, then they know. But no one has said anything to me (yet). If they do, then I will come clean with them.
