Common meaning:

Sexual feelings for the opposite sex.

Hidden meaning of the Equity religion: 

Constructed by subjective feelings and in no way connected to biology.

Discussion:

The Equityists believe that sexuality is totally created subjectively by individuals who are part of particular groups. The feelings of sexual attraction that are experienced by people are in no way connected to biological processes. 

How a person feels sexually is the one and only basis on which we are to judge if a particular sexuality exists. This makes sense religiously when we understand that people with minoritized sexualities must be listened to without being questioned. 

Back in the real world, we find that in a properly functioning human, the sex of the individual determines the physical manifestations of organs and the creation of sex organs specific to one of two sexes (male or female). Once these are created, there are no options for any other genders or sexualities, despite the illusions that some have invented in their minds.

Your chromosomes don’t care about your feelings.
