Asexual (commonly shortened to ace) is an orientation defined by experiencing little to no sexual attraction, the prefix a- meaning not or lack of in Greek.

Being asexual does not mean that one is unable to experience romantic attraction or any other type of attractions. An asexual individual can have any romantic orientation. They may identify with a romantic orientation in addition to the label of asexual to specify who they're interested in romantically, if anyone. For example, a heteromantic asexual individual is romantically attracted to individuals of a different gender, but is not sexually attracted to any gender. Some asexual individuals are also aromantic (aroace), meaning they experience neither sexual nor romantic attraction.

Sexual dispositions among asexual individuals can vary. Some asexual individuals may still masturbate or have or seek sexual relationship(s) despite not feeling sexual attraction to anyone (cupiosexual). This could be for many reasons, such as for their own pleasure, their partner's pleasure, desire for self exploration, or feeling that one's attraction is not an important aspect to partaking in their sexual relationship(s). Other asexual individuals may be repulsed by the concept of sexuality. Terms like sex-repulsed, sex-indifferent, sex-favorable, or sex-ambivalent are commonly used to describe these attitudes.

A common misconception is that all asexual individuals are either celibates or practicing abstinence. Those who are abstinent or celibate are not necessarily asexual; they may still experience sexual attraction but choose not to act on it, typically for moral or religious reasons.

Aromantic (commonly shortened to aro) is an orientation defined by little to no romantic attraction, the prefix a- meaning not or lack of in Greek.

Being aromantic does not mean that one is unable to experience sexual attraction or any other type of attractions. An aromantic individual can have any sexual orientation. They may identify with a sexual orientation in addition to the label of aromantic to specify who they're interested in sexually, if anyone. For example, a heterosexual aromantic individual is sexually attracted to individuals of a different gender, but is not romantically attracted to any gender. Some aromantic individuals are also asexual (aroace), meaning they experience neither sexual nor romantic attraction.

Romantic dispositions among aromantic individuals can vary. Some aromantic individuals may still have or seek romantic relationship(s) despite not feeling romantic attraction to anyone (cupioromantic). This could be for many reasons, such as for their own pleasure, state benefits, household aid, or feeling that one's attraction is not an important aspect to partaking in their romantic relationship(s). Other aromantic individuals may be repulsed by the concept of romance. Terms like romance-repulsed, romance-indifferent, romance-favorable, or romance-ambivalent are commonly used to describe these attitudes.

A common misconception is that all aromantic individuals lack emotions, lack the ability to form social connections, or are loveless. In reality many aromantic individuals are capable of feeling love, and can meet their emotional needs via queerplatonic, platonic, familial, or other non-romantic relationships. Other aromantic individuals may not desire partners of any kind, and may identify as nonamorous. Some aromantics embrace the loveless label and reject the idea that love is necessary for their own wellbeing and happiness.

Asensual is an identity on the asensual spectrum defined by a lack of sensual attraction. Asensual experiences may also include: 

• not wanting to touch others 
• and/or be touched by others, 
• not being interested in sensual activities, 
• or being repulsed by touch. 

Sensual attraction is defined as the desire to have nonsexual forms of touch such as cuddling, kissing, or massage with another person in particular. For allosensual people, sensual attraction is involuntary, and possibly even occurs when someone doesn't know the other person (though one might not act on it). Asensual people do not have this innate desire to have sensual touch with any specific person. They may also feel disconnected from the idea of engaging in sensual activity.

Some asensuals do engage in sensual activities. This could be for any reason, such as meeting their own sensory needs or those of a partner.

Being asensual does not mean that one is unable to experience sexual attraction or enjoy sexual activity. An asensual person can have any sexual orientation. Asensuals who are repulsed by or indifferent to sensual (nonsexual) touch may greatly enjoy sexual touch. Asensuals can also have any romantic orientation and tertiary attractions.

Ansthetic, also known as a-aesthetic, nonaesthetic, or anaesthetic, is a form of attraction where one does not feel aesthetic attraction or doesn't get the concept of aesthetic attraction. One can still be romantically or sexually attracted to someone (or even both), but their attraction does not revolve around one's appearance.

One may abbreviate the term anaesthetic to anae, nonaesthetic to nonae, and a-aesthetic to aae; one may abbreviate the ansthetic spectrum to ae-spec.
