i'm out with my bicuriousity.. but i think it helps that I can tell my parents anything. I'm very open with everyone, basically have the "i have nothing to hide" attitude. Though with me, my parents basically approached me about it with their suspicions. I have a friend who's lesbian and i keep telling my parents the wise cracks she makes that makes me laugh. I guess my parents realised how happy I was hanging out with her and since my brother is 18 and not very accepting of any of my choices, they wanted to know to prepare him for anything.
It was easy for me, and they are very accepting. I figure they've been through things too, particularly not this but in each generations there are things that parents have got to understand. and with me, its interacial dating and bi-sexuality. who knows maybe its more than curiousness but i'm glad they are open about it.
CindyLou, no matter how many times you rehearse it, it won't happen that way. I know its hard to face but like you said, they've got to know. It may help rebuild relationships with your sibblings, but what ever happens, you came out and did what you could, the rest is in their hands. Good luck hon.
