That's why I think codes like this are a good idea: it succinctly summarizes a persons complete orientation, which has a significant chance of being a convoluted mess (we are, after all, only human) and one word (like asexual, pansexual, bi, straight, etc) can't and shouldn't be expected to cover the depth and richness of possibilities.
It's very nerdy, I like it ..and then there are people who say "why does everyone have to be a special snowflake, just conform to everyone...." ಠ_ಠ ..just jealous that others are more interesting and have the cognitive faculties to comprehend numbers higher than two and concepts more involved than their own simple life/ perspective.. I mean the animal kingdom is f*'ed up, it's awesome ~ people should just do what they want...
