Aegosexual is an identity found on the asexual spectrum, used to describe two similar, but subtly distinct, kinds of sexual attraction and behaviour:

(a) an individual that experiences arousal at the thought of sexual behaviours, but experiences no or little sexual attraction towards other people; or,
(b) an individual who experiences sexual attraction, but does not want to participate in sex or sexual behaviours.

For an example, an aegosexual person may masturbate, watch pornography, or watch other sexual content, but still not desire to engage in sexual experiences with other people.

Or, an aegosexual individual may fantasise about watching other individuals engage in sex, but not about in engaging in it themselves.

Aegosexuality was previously known as autochorisexual, a term coined by Dr. Anthony Bogaert, a psychologist that specialised in human sexuality; however, it was considered a kind of psychological disorder (along with asexuality in general). Whilst some within that identity attempted to reclaim the term, others felt uncomfortable with the negative connotations, and aegosexual was coined by a Tumblr user named Sugar-and-Spite.

The etymology of aegosexuality is comprimsed of: a (without) + ego (oneself) + sexuality.
