Telling the family...

I've recently decided to accept the fact that, though I was born female, I am definitely a guy. I want to tell my family, but I don't know how. My Mum is generally quite accepting and I think, given time, she'll be okay with it, but my father is a complete homophobe and quite often bags out people from the lgbt community, which I have been part of since I was 14... Not that he's aware of this... Please help!
