There's also the whole aspect of how "bisexual" isn't entirely taken seriously as a sexual orientation, especially because a lot of bisexual women end up married to men. (Of course, that's actually because there are a lot more men interested in women than women interested in women rather than because someone who claims to be Kinsey 3 or above is looking to settle down with a member of the opposite sex in the end.)

But yeah, I kind of feel like that too - both invisionary and I are bisexual, so by that logic neither of us should have ANY friends. :P
