Well, about two years ago, shortly after I got back from my first Philadelphia Trans-Health conference, my son came out to me as trans. In fact, they were the one who got me to start HRT a couple of months later, and I went with them for their first visit to the sperm bank. (They want to reseve the option of having children.)
I don't know how much support I've been to them. They're on the autistic spectrum, so they're not good about talking about feelings, and what is being trans about if not feelings? But they spend most of their time on (or is it in?) Second Life, so maybe they're talking about being trans and trans feelings and such in Second Life.
