Asexual (often shortened to ace) is a sexual orientation defined by a lack of sexual attraction. Asexual experiences may also include: not wanting to have sex, not being interested in sex, not experiencing a sex drive/libido, or being repulsed by sex. Sexual attraction is defined as the desire to have sex with, or otherwise perform sexual acts with, another specific individual. For non-asexual individuals (allosexuals), sexual attraction is involuntary, and even occurs when someone doesn't know the other individual (though one might not act on it). Asexual individuals do not have an innate desire to have sex with anyone. They might also feel disconnected from the idea of sex.
