Illusogender

Illusogender is when someone one knows they're a certain gender, but there's still the feeling of ‘fakeness’ present, either due to neurodivergency or due to outside pressure, such as from parents, society, etc. These feelings and/or pressures can be part of the gender experience.

Illusogender can be combined with the relevant genders one feels. For example: illusoboy, illusogirl, etc.
