DISCLAIMER: Identity words are difficult to understand and even more difficult to coordinate based on how people are comfortable identifying. This goes for any and all words, and that’s fine. If someone doesn’t want a word used to refer to them, forget what you think you know about the meaning of a word and go with their preference. 

ace – a term casually used to refer to someone who is asexual.

aesthetic attraction - a term used to describe attraction based simply on how someone looks, entirely unconnected to any desire to have anything to do with them either romantically or sexually.

agender – someone who identifies as neither male nor female, nor as somewhere between the two as with a number of other non-binary identities (such as genderqueer or androgyne); same as genderless and similar to neutrois.

antisexual – different from asexual, antisexual communicates an actively antagonistic view towards sex and sexuality.

aromantic – although most generally used to describe someone who does not experience romantic attraction, there is no set definition for “aromantic,” and is often left up to individual interpretation.

AVEN - Asexual Visibility and Education Network; the functional hub of the asexual movement, it serves as both a community of asexuals and a source for visibility efforts, both through asexual-generated projects (pride festivals, zines, etc.) and as a source for those outside of the community to gain information and volunteers.

homoromantic – someone who experience romantic attraction to their own gender.
