Asexuality is a sexual orientation because it describes a person’s pattern of attraction (to no one). Asexuality is a mature state because it isn’t a term for what a person is before they develop their sexual orientation. Asexuality is a description because it is a word for explaining an experience, not a decision or a choice. Asexuality is a healthy status because it is not considered a mental or physical illness to not desire, pursue, or feel attraction that leads to sex. And it is a reasonable possibility because feeling sexual attraction or inclination toward others is not the default.
