Consexual is the orientation which suggests one is sexually attracted to someone the more they resemble themselves. Someone's presentation, personality and potentially other characteristics might play a part in someone's desire to create a partnership. This may or may not be specific; for example, an androgynous demigirl might have attraction for fellow demigirls, or it may go as far as (or further with) androgynous demigirls, etc. This differs from having a preference because it can be an exclusive attraction or involve pronouns, expression, etc. Consexual can be an ace-spec (aka con-ace) or allo orientation, depending on the amount of similarity it takes to be attracted in the first place which provides a lot of flexibility.
The romantic counterpart is conromantic. The neurodivergent-exclusive counterpart is neuric.
