As someone who relates a lot to the feeling OP is describing, I actually blocked that community. Feeling uncomfortable with the label “woman” and the baggage it comes with, a place that’s labeled “for women only!” is one of the few things I’ve encountered that made me sympathise with what actual gender dysphoria must feel like.

Or:

• a gender-non-conforming woman
• an enby
• someone who’s gender fluid
• some flavor of neurodivergence, BPD, or any other issue associated with an ambivalent sense of self, overestimating how much one should feel like “x” in order to “deserve to be called x”
• a person in the process of discovering their own gender identity

So let’s not jump to conclusion. There are many options and being a trans man is just one of them - and one we should never hastily impose on anyone.
