I can't help you when it comes to disclosing information to family or loved ones, as I haven't been able to do that myself except for the rare occassion. I don't want to bring up the negatives to dissuade you, but I have never felt enough trust to tell my parents, or even my wife.
Why I am posting is because you mentioned the possibility of having children. I always thought I never wanted to have children, but when I had my daughter, it is probably the happiest thing that has ever happened to me. Just seeing her each day helps me stay more balanced.
I do get criticised of being over protective of her though, much like ALovingMum was talking about. Last thing i would ever want to happen is for my child to experience what I have been through.
