What I'm asserting is that we are looking at bisexuality the wrong way, making the identity entirely dependent on someone other that the bisexual person him- or herself. If I'm dating a man, I'm straight. If I'm dating a woman, I'm a lesbian. But sexuality is not who you sleep with, it's who you are. It doesn't change according to who is standing next to you.
