My hole life i felt uncomfortable with myself, since I was a kid. I remember seeing a soap opera when I was like 10, where there was this feminine character that was a hermaphrodite. That really got into me. Of course, at the time, I didnt really understand what a hermaphordite was, but, a character that was born with a penis and then became a woman (thats what I understood at the time, of course)... wow... just, wow... I spend a lot of time back then wishing that I too was like that girl in the tv who was born a man. Of course, later, I learn that was not the case... but that didnt change what I felt... When I was even younger, I remember having a toy with interchangeable parts that you use to make a draw. It had 3 different parts that together form a character for your draw, Legs, Torso and Head, wich you could combine. It had a human, a lizard man, and another one that i cant remember, but, I always made the human head and torso with the lizard legs, because (and that was concious) the lizard man didnt had a penis.
Or course, for a long time, i didnt realize that I am trans. To this day, sometimes I still think that i'm not "trans enough" (like Peep said), so, I still havent trasitioned. Kinda crazy, i guess...
