Amorasexual (ah-mor-ay-sex-u-al) is an ace-spec identity under the aliquasexual umbrella. Amorasexual is defined as only feeling sexual attraction to a person (or people) when in a sexual relationship, or sexual context with them.
An amorasexual person may know that they may enjoy a sexual relationship with someone but will not feel attracted to them until in said relationship. They may also feel attracted in sexual contexts (i.e. discussing beginning a sexual relationship but not officially being in one). This label may be used by anyone as either a standalone label or in combination with other labels.
A sexual relationship may include a romantic relationship in which sex is implied, a friends-with-benefits-type relationship, or any other relationship where sex is implied or focused upon. Some amorasexual people may need both a sexual relationship and sexual context in order to feel sexual attraction (i.e. being in a relationship where sex is implied and presently discussing sex).
The romantic equivalent of amorasexual is amoraromatic. if one identifies as both amorasexual and amoraromatic they may be called amorain.
