I am one.
Just for those who are uninformed on the matter, not all sociopaths are evil/harmful/violent etc, it's much more of a spectrum than that. I personally am a high-functioning sociopath, and I fit in with society about as well as could be expected from any sociopath; I mostly just lack empathy and a conscience. By which I do not mean that I don't know the difference between right and wrong, or that I partake in wrongful acts, but that I do what is good because doing what society deems wrong is illogical.
Generally speaking sociopaths are very changeable, and can shift personality or appearance for a bunch of reasons. Many even lie to themselves about who they are. I'm wondering if this is perhaps why it took me so many years to realise that I was trans; I spent all of my youth changing myself to conform to what other's expected me to be, and to fit in with those that I was interested in, that I think somewhere along the way I lost track of the part of myself that was the real deal.
On the other hand, perhaps being this way has liberated me from a lot of the troubles 'normal' trans guys have. I do not think in any way that what I'm doing is wrong (as some trans guys can feel at the start), it doesn't give me a sinking feelings to think of other's reactions, and social and emotional connections are nowhere near as important to me as they are to others. If a family member or friend has a problem with me, I cut them out of my life; it's not even a slightly difficult thing for me to do. And acting as if I have always lived in a male body and deflecting unwanted comments is easy, because I do not feel any of the guilt or unease some trans people do when 'lying' (I do not mean that saying you are male is a lie, but that some guys can feel guilty for not telling the whole truth behind it).
I'm just wondering if this is common in the trans world, or if there are any other guys who have been through this?
