Interesting thread... Trans means moving from something to something, so technically if we were born a genetic male, or female, but are wired for the opposite sex, then through the path to get to the right genetic physical state we chose, we are transgender'ing from one to the other.
So personally it's a description of a journey, not a person or sexual state... So I agree with Danielle and Peky... However at this point in time I am transgender'ing and therefore OK, will I be OK once there? ...Can't answer that yet, certainly won't deny the journey, but would prefer to be known as a women...
