What is something you learned or experienced from being trans that you wish you knew pre-transition, or that you wish cis people knew?

I'll go first: the temperature differences when going from testosterone-dominance to estrogen-dominance is not just real but significant, my body just puts out less heat and I feel colder much easier now even when otherwise maintaining a high metabolism, eating in excess, etc.

It may have just been my trans denial before, but I really wanted to believe that the difference was not that great and I was wrong.

What's something you wish people knew?
