Asexuality is a sexual orientation. Asexual people do not have sexual feelings for anyone, neither male nor female. Asexual people may still feel different kinds of love for others, but don't experience sexual attraction. Asexuality is different to not having sex (celibacy). Some asexual people masturbate or have sex. Asexual people can also enjoy sex.
In 2001 David Jay started the Asexual Visibility and Education Network. 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.
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 asexual people identify as queer. However, some people think that 'queer' is not an appropriate word for asexual people.
