I've dealt with this in real life, as my ex is a female to male CSA survivor. And from knowing him intimately, it caused me great distress because I knew he was not like a guy mentally. I want to be completely supportive of transgendered individuals, but from my personal experience, a transgendered male is not the same as a biological male, especially so before they have gone into treatment. There is just a hugely different dynamic between biological men and women as to how they process things emotionally. Sometimes very very minute differences, yet very distinct. Something only intuition picks up on. Again, this is only from my experience knowing transgendered people and I've only known 3 in life, so I am by no mean an expert. But there is one thing I do believe, and that is that human biology plays into human psychology so whether or not they identify as a male or female, their psychology is affected by their biological anatomy until they change it.
