No idea how to tell my mother

I don't think "genderfluid" is really a term that most people outside of the LGBTQ+ community are familiar with, so that fact that she understands that concept is actually not a bad start. If she asked you about it in a non-accusatory way, it sounds as if she might not be too threatened by gender variance in general. When she asked you about genderfluidity, did she seem like she would have been alarmed if you said "yes"?

Since you had that talk already, one approach might to be say "Remember that conversation we had about people who are genderfluid? Well I still don't think that's exactly the right label for me, but I don't think I'm completely female either." She will probably need some education about gender variance, and plenty of time to think about all of this. My sister is trans*, and when she came out to my mom, her main concern was just my sister's safety (i.e., because of transphobia/bashing). If you're willing to talk to your mom about what you can do to avoid situations where you're endangered by this sort of thing, I bet that would go a long way towards comforting any distress she might have.

This is a really big step, but it sounds to me like it should go pretty well! Good luck!

 

I understand this to a degree, because my mom isn't homophobic but she was derisive when I said I was a lesbian - like I was confused, in a phase, looking for attention, etc. But she is S L O W L Y coming to accept it. Good luck. I hope you do get to tell your mom, and that she's okay (even happy) with it. Who knows? But come out when YOU feel ready to.

 

Good luck to you!

 

Sorry dude. Getting replies like that always suck. I hope everything else goes well for you.
