As usual, Reine asks the important question. What do you mean by "trans"?
For myself, I take the term transgender to be someone who takes on, or has, some aspect of what is typically considered to be the gender opposite their birth one. Transsexual, is someone who feels they were born in the wrong gender, and such individuals may consider or need to transition to the appropriate gender. I know this is a gross over simplification, but this my particular slant on it, and is put forth for the purposes of my answer.
I accept that what I do (wearing skirts and hosiery as a man)is crossdressing, but I don't feel it is such in my own mind. I also accept that by most psychological definitions, I am trans gender, because I am using physical display and gender display of the opposite gender, and thus I appear somewhat feminine. My issue with that, is that the current accepted definitions of feminine and masculine are too rigid and will benefit from some loosening up.
