Asexuality is a sexual orientation. Asexual people generally do not have sexual attraction towards anyone, no matter what gender they are. Asexual people may still feel different kinds of love for others, masturbate or enjoy sex, but generally don't experience sexual attraction. Not having sex (celibacy), is not necessarily asexuality. Some homosexuals, for example, refuse to engage in sex because they feel guilty about their sexual attraction.
Asexuality is described as a spectrum. Demisexual people are on the asexual spectrum. They experience sexual attraction, but only to people who they feel an emotional connection to. About 1% of people self-identify as asexual. Alfred Kinsey used the label "X" to describe asexual people.  Grey-asexual people are people who feel like they are not asexual, but they're not sexual either. For example, a grey-asexual person could experience sexual attraction very rarely. Some asexuals also identify with a romantic spectrum as well. Meaning they may feel the need to form relationships or have romantic attraction, while others may not. Some asexual people identify as queer. However, some people think that 'queer' is not an appropriate word for asexual people.
In 2001, David Jay started the Asexual Visibility and Education Network. A 2012 study found that asexual people are more discriminated against than gay men, lesbians, or bisexuals. Asexuality has only recently been studied. One writer, S.E. Smith speculates that it has not increased, its just people have only just started noticing it.  Acceptance of asexuality as a subject of scientific has only begun recently.
