Potensexual is an orientation where someone only feels sexual attraction to those who could potentially reciprocate by the definition of their orientation. For example; a potensexual pansexual woman is only attracted to another woman when they know that they are WLW. The romantic equivalent is potenromantic.
It may be seen as the opposite of proculsexual.
The prefix Poten- is from the word Potential, which describes the core aspect of potensexuality.
