You found your feminine energy -- that's good. Every decent magician needs to learn how to work with both the female and male energies we hold within ourselves. Everyone has both, I'm not sure if that's the only reason you id as non-binary but you don't have to be something other than your assigned gender just because you found out you have a fair amount of female energies.
Female energies in magic are essential for works relating to intuition and are great help on works of divination and enhancing your astral senses -- pretty much anything that is related to the processing of information.
Make sure you understand the roles of male and female energies in a ritual context before trying to apply that.
You don't need to contact a female entity to do that.
