A little language pedantry for y’all this evening:

Aficionado (masculine) and aficionada (feminine) are Spanish nouns for a fan, enthusiast, or devotee of a subject or hobby. They distinguish gender, with aficionado used for males (or mixed groups — aficionados in plural) and aficionada for females.

So if you are a woman, I recommend using aficionada. Otherwise just say you’re a fan. And forget about genders.
