Most of my friends know I'm bi. Actually, my real friends know I'm bi and some other people do, too. The biggest problems I've had attitude-wise come from the boyfriends and husbands of my close female friends. They've often ended up getting weird around me, sometimes even a little mean. It took forever to figure out that, even though I don't bonk their ladies, I am both temptation and threat.
Oftentimes the first thing they'll say right off the bat is that it's okay with them as long as they can watch or join. I tell them my sexuality is about me, not them. (And if I have to say that to a guy I'm dating, there won't be a next date). So for the boyfriends and husbands, it seems they're turned on by the thought of me being with their ladies, and pissed because I might go for it and they won't get invited. Then I have to have their ladies explain to them that if I were going to go for it, I would have done it before we actually became close friends. Ugh, maybe I should just keep my mouth shut, but why should I? My sexuality is a part of who I am, and my real friends know who I am.
Zara, this is what I envy about your generation, that there's so much openness about bisexuality. I didn't talk about it for most of my life because I felt guilty, and telling someone was a huge risk. And for bi's, what was the point in taking a risk? We had everything to lose and, unlike gays and lesbians, nothing significant to gain - with the exception of the bi's who can nest with either gender because that's how they're programmed. Me, I don't nest with girls, it's not how I'm programmed, so the only reason I used to have for telling someone was if I was hoping to get in a girl's panties, ergo The Risk.
As far as your religious beliefs go, well...if I were ever forced to have a baby I would only keep it if it were a ginger, otherwise I'd let you eat it.
