I just came out to my best friend over facebook. It was a devious plan. I was chatting to her and just casually mentioned that I was bi. She said 'yeah, I know' (which is quite a feat considering she's the first one I've told) and that was that. YAY!(!)
Congratulations on coming out to your first person! (*hug*) You've taken a huge leap, and trust me after the first one, it gets easier! Just make sure you tell the right people!
