Suptiliasexual

Suptiliasexual, also known as suptili-ace, or suptilic asexual, is a term referring to someone who is purely asexual, not grey ace or elsewhere on the asexual spectrum. A suptiliasexual individual has never, and will never, feel sexual attraction. It is similar to omniasexual, but those who are suptiliasexual may be okay engaging in discussions about sexual acts.

Etymology
Suptiliasexual comes from the Brazilian expression assexual estrito(a/e), which means "strict asexual" in Brazilian Portuguese. In Brazil, the word asexual is an umbrella term for the entire spectrum. Someone fully asexual would be assexual estrito(a/e). In English, these individuals would usually just be called "asexual;" however, the term suptiliasexual is useful for differentiating between suptiliasexuals and others on the asexual spectrum.
