When I came out to my mom, her exact words were "this is not news to me." Apparently she knew, or at least suspected since I was a toddler. In fact, she had been describing me to people as "my daughter is a man in a woman's body" for years before I ever came out. My dad said he'd had suspicions as well. No one else has ever said anything, but most people have treated me like a male for most of my life.
