@LouisIngenthron Automobiles isnt a sex, neither is furry, therefore it isnt an orientation.
A sexual orientation is not "a think you are attracted to".. liking big boobs isnt a sexual orientation. In fact im hesitatant to even put P in there, as its borderline. Butit at least describes the scenario of needing a man and woman at the same time, so it is somewhat relevant.
Since only 2 sexes and exist and there is nothing between poly and and mono, then yea you can fit people into nice boxes as there is a fairly finite number of combinations.
