Thanks for sharing Emma, the way I see it you are trans* by all means, no question about it and I say that in a good way. And I enjoyed reading this blog entry.
IMHO it is not the clothes, heaven forbid I am not one to put on makeup and fancy clothes to say to the world "Hey, I am female". My best friend is relentless in trying to get me to purchase very pretty outfits but I will not have that. I agree to somewhat that it's between "here" that indicates I should be female or I should be male dependent on the person but to me, it's in my head. There are days in the past year I went out to teach a class and wore the appropriate clothes and not even attempt to look female but yeah I did and that is just fine with me. In the end I am comfortable in jeans with my hair in a ponytail.
PS I am not one for sitting in a group to hear myself chat with others but instead a willing participant to share knowledge that benefits the group.
