I have recently changed my sex and socially imposed gender through a MTF transition process. I identify as female (and prefer gendered references to be feminine). Of course, my gender identity has always been female. I will be putting in a few lines on my slow and rapid transition phases soon on this page. Orientation-wise I am a lesbian. I am being a bit open ... because, I want to make the world a better place to live in for others. You can find more about my transition at my personal blog.
Some Clarifications: I follow this definition: From a scientific point of view, the sex of a person can be seen as a long tuple of parameters corresponding to representations of hormonal data, clinical sex, brain sex, chromosomal sex and others. This needs more than seven clusters for classification (if at all possible) . The concept of 'gender' in contrast is very unscientific and corresponds to a set of socially constructed, assigned behaviors and identity patterns that may have little to do with the scientific concept of sex. If the notion of gender cannot be excluded in a backward society, then the best alternative to avoiding gender would be to assume that the "gender of a person is what the person says it is". For more on this you can see my write up on the topic.
