Someone who does not experience sexual attraction. Unlike celibacy, which people choose, asexuality is an intrinsic part of who someone is. There is considerable diversity among the asexual community; each asexual person experiences things like relationships, attraction, and arousal somewhat differently.

Some asexuals do participate in sex, for a variety of reasons.
