Asexuality is a sexuality in which a person does not experience sexual attraction to another person. This is not the same as celibacy or abstinence, in which a person may experience sexual attraction but refrains from sexual activity. Additionally, this is separate from the aromantic identity, which describes people who experience sexual attraction but experience no romantic attraction. While some asexual people still choose to engage in sexual activity, they generally do not feel the need to do so. The asexual umbrella includes some identities such as demisexuality and grey-asexuality. One of the most prominent asexuality groups is the Asexual Visibility and Education Network (AVEN).
