Sexual orientations are typically thought of as being heterosexual, homosexual, or bisexual. Recently, however, some researchers have proposed that asexuality is potentially another sexual orientation. Asexuals are people who are not sexually attracted to other people.
Researchers who have studied human asexuality have focused on different definitions, such as a lack of sexual orientation, lack of sexual behavior, and lack of sexual desire or excitement.
Some researchers have suggested that asexuality may simply be an extreme case of low sexual desire disorder. However, asexuals oppose this idea. They do not want a cure for their lack of sexual attraction and are not distressed by it. Many resist the idea that asexuality should be labeled as a disorder at all. They argue that asexuality is better classified as a sexual orientation.
