I'm no expert in cis men but cis men aren't usually traumatized by their own masculinity
I wasn't "socialized as a girl" growing up either. I didn't have a normal adolescence. Many trans people spend years in the dark not knowing why they're different and the pressure to act otherwise is devastating.
I never learned how to form friendships. I have a complicated relationship with physical intimacy, even with friends. My body repulsed me in ways I had no words to describe. I felt like an alien among my peers and became a social recluse in middle school. NONE OF THAT IS NORMAL!
