I don't tell many people that I am bi-sexual. Why? It confuses them. No, seriously, they get all discombobulated and don't know what to think. If I tell a straight woman that I'm bi she automatically worries that I've been checking her out and if they happen to have read any of my stories they really worry. And if I tell a guy I'm bi he starts fantasizing about me and him and some other chick.
I don't sit around and fantasize about my co-workers - they are my co-workers and I don't mess with that even though one of them is kinda hot. But she's totally straight and even if she wasn't I just wouldn't got there. I don't imagine my girl friends naked and I don't hit on other girls. I'm not dangerous - I swear. I've had one relationship that developed from a friendship. That's it. Yet I know that if I met someone that happened to turn me on and showed some interest and my fiance was OK with it, yes, I'd go there again. But my commitment is to my fiance so that means that I'm not in a position to get into a real relationship. Do I crave pussy? No, I don't. I enjoy being with a woman but I don't dream about it.
I also don't actively go out searching for a third partner in my relationship. My fiance and I have discussed it and we may go there at some point but it isn't a huge goal for us.
Being bi-sexual does not mean that I am a big horn dog looking to get action from men and women. Be bi-sexual does not mean that I need both men and women to be satisfied. Being bi-sexual does not mean what a lot of straight people think it means.
It simply means that there are some women I find attractive and there are some women I would consider being sexual with and there are some women I might meet that I would consider inviting into my bedroom with my fiance. It also means that I find my male partner very attractive and am very happy with him and will be happy having him as the only partner in my life if that is what we chose.
And that's why I don't tell many people in my real life that I am bi-sexual.
