Anogender

Anogender (or Anagender) has been defined as a gender which fades in and out in intensity but always comes back to the same gendered feeling. It was coined in 2014 by tumblr user pocketmouse:

"a feeling of gender that fades in and out but feels the same whenever it comes back. different from genderfluid in that it’s one gender constantly resurfacing, rather than switching between genders".
