Well, haven't you said elsewhere that not only do you have a boyfriend, but might be pregnant? Are you seeing two (or more) people of different sexes now?

Why do you feel you want to announce being bisexual, anyway? It seems strange that "a lot of people know" except your three best friends. Maybe they already know and they don't care? It sounds like you are looking to shock them just to get a reaction. It doesn't seem like it should be any of their business, or if it is something you want to talk about with them, then just bring it up normally, like it's no big deal. If you start going out with a girl, just say, yeah, you're bisexual, and right now the person you fancy most is female.

I think you should tell them, just sit them down one by one and explain thats you can't change yourself and that they should accept you for who you are. If they are true friends they will accept you. As for family, they should understand too. Its hard for me to judge though, I too am bi and most of my family are very religious except for my mum and sisters. I didn't really see the point in telling all of my family (grandparents etc) because I havn't actually dated a woman before.
Good luck anyway.

Just tell them .. I told mine and only 1 of them wasent cool with it. The rest are like kayla do I look hot like that .. They think its cool ... And they love my girl friend. Chances are one of them is bi there self.

Well...If your friends/family now about your other sibling that is bi think of how they reacted to that and base your decision on that. But you should tell them becuase they really wouldnt be your friends if they didne accept it.
