Asexuals are generally considered to be adults who are largely or completely devoid of sexual drive, attractions, feelings, or desires towards other people. They typically have little or no interest in sexual activity. However, some do engage in sexual behavior out of a sense of duty, to procreate, to please their partner, or perhaps for other reasons.
Recent studies at Brock University in Canada have indicated that feelings of prejudice by the general population towards asexual persons exists at a higher level than even prejudice against the LGBT community.
Asexual persons are different from celibate individuals. The latter typically have sex drives and attractions towards others, but have decided for personal or religious reasons to not engage in sexual activity.
Asexuals appear to be rare. A study in Britain found that only about 1% of respondents agreed with the statement: "I have never felt sexually attracted to anyone at all."
Some specialists in human sexuality regard asexuality as a fourth sexual orientation, in addition to heterosexuality, bisexuality and homosexuality. Others consider it to have a lack of sexual orientation.
