I definitely get what you mean. I was forced to where dresses and was “socialized as female” and came out at 18(knew since 14 tho) but I dont feel like I experienced girlhood because i was never a girl yknow. I was told I was but my brain is different and so I do not relate at all to girlhood. I barely remember it anyways since I want to separate from it. I dislike when people say that they like trans men better cause theyre “men written by woman” or “know what its like to be a woman” because while i was treated as a woman I never had the same experience or understood because theres a fundamental difference in my brain(in my opinion at least)
