Labels are just succinct words/phrases that try to give people some approximate idea of where we fall on a handful of vast spectrums. They're not meant to be 100% accurate.

I'm probably pansexual, but I tell people I'm bi because that's a word most people are familiar with. And even then I'm like 80-90% into women. So I don't really fit neatly into the bisexual box, but that label conveys enough relevant information.
