Yay! Coming out stories!
I came out to my mom when I was 19 and I think it might have been one of the hardest things I've ever done. I think in some ways, it can be harder to come out as bisexual because you have to explain the "liking both" part.
It's been 10 years now, and Mom's only just starting to be able to casually talk about the idea of me having a girlfriend (although, it may be easier for her to do since I'm single at present and it's all hypothetical)
My friends were pretty much universally great when I came out to them. I called my best friend at the time and told him I had something to tell him - and he said "actually, I was just going to call you..." We came out to each other on the same day
He had planned to tell me sooner, but he'd just broken up with another friend of mine and he was worried that, if I'd known, I'd have tried to get them back together again (hopeless romantic that I am :lol: )
About 3 months after I came out, another friend of mine (a girl) told me that she had feelings for me. We had a really brief relationship and she was my first girlfriend, but she refused to either admit that she was gay/bi or to ever come out to anyone (not even our close friends). We had to sneak around and, after all the trauma of coming out, I just couldn't go back into the closet like that, so I ended it. To this day, I'm pretty sure she's never come out, although I do know she's had a few relationships with women. My heart breaks for her that she cannot accept her own sexuality and she feels the need to hide it from the world. But it's her choice.
