Rats. You are way to cute for me to disagree with Troy, sigh.
I feel pretty safe here at soulforce, so I'll let you in on a secret. I identify as "gay." I've come out, at huge expense, as "gay." But I sometimes fear I might be "bisexual." That's bisexual, not ambisextrous. I say "fear" because I have never had an opportunity for a ltr to actually see for myself. I do know I'm mostly gay, the evidence is all there, but there's enough to make me question also. I actually fear being bisexual because many see bisexual people as people who have a choice. For a bisexual to choose is like saying: "which to you want to keep, your right arm or your left arm."
As Zerbie is trying to explain, it isn't like you have this wonderful choice and you can go either way, rather, you feel a loss if you don't have both. Just like you would have a real void if you were forced to be with a woman, a bisexual person has a very real void if they don't have both.
I think it is harder to be bisexual than it is to be gay in some respects.
