Asexuality [SEP] Introduction
Asexuality is the lack of sexual attraction to others, or low or absent interest in or desire for sexual activity. It may be considered a sexual orientation or the lack thereof. It may also be categorized more widely to include a broad spectrum of asexual sub-identities. Asexuality is distinct from abstention from sexual activity and from celibacy, which are behavioral and generally motivated by factors such as an individual's personal, social, or religious beliefs. Sexual orientation, unlike sexual behavior, is believed to be "enduring". Some asexual people engage in sexual activity despite lacking sexual attraction or a desire for sex, due to a variety of reasons, such as a desire to pleasure themselves or romantic partners, or a desire to have children.
