For me, disclosure has been a positive thing. Of course the first person I disclosed to was my wife. She had known of some of my past with other men but never to the extent as being sexually abused. Since I've "come out" so to speak, she and I have had an on going dialogue about my abuse ever since. Now she knows every sordid detail and hasn't batted an eye.
The only other people I've disclosed to have been my brother (by phone) and my father (by short email) and they both responded well. My family isn't all warm and fuzzy so I didn't get smoochies from them but at least they havent' shunned me - yet.
My bosses know to a small degree only because I have PTSD and weekly sessions with my psychiatrist so they have to know because of how it effects my job as a department head. They've been supportive and have taken some of my resposiblities away for a while until I can reach a level of recovery that will allow me to be able to handle the stresses that I would ordinarily have to deal with.
Anyway, all of our situations are different. Disclosure to the wrong people can be damaging. Be wise to whom you reveal your story to. You could be set back or leapt forward in your recovery dependant upon who you tell. It's very thin line we walk my brother. Who do we trust...?
