HI,
According to the Susan's Place WIKI...."Transgender is the state of one's "gender identity" (self-identification as woman, man, or neither) not matching one's "assigned sex" (identification by others as male or female based on physical/genetic sex). "Transgender" does not imply any specific form of sexual orientation; transgender people may identify as heterosexual, homosexual, bisexual, pansexual, polysexual, or asexual. The precise definition for transgender remains in flux, but includes:
"Of, relating to, or designating a person whose identity does not conform unambiguously to conventional notions of male or female gender roles, but combines or moves between these."[1]
"People who were assigned a sex, usually at birth and based on their genitals, but who feel that this is a false or incomplete description of themselves."[2]
"Non-identification with, or non-presentation as, the sex (and assumed gender) one was assigned at birth."[3]"
So, if your assigned gender and your gender identity are different, you are transgender.
the term "Transsexual" gets problematic. Again, from the WIKI, "The definition of "transsexuality" is somewhat debated. One common definition is that a transsexual is a person who believes that his or her body does not reflect his or her true 'inner' identification of physical sex or gender. Another common definition is that a transsexual is a person who has had or plans to have medical or surgical treatments that alter his or her body to better reflect what the individual believes is his or her true gender. The first definition allows greater freedom for individuals to self-identify as a transsexual. The latter defines the term based on actual or planned operative status and makes it more an external label than a term of self-definition."
The first really seems to describe transgender and the second, transsexual. I tend to use the second part of the transsexual definition for transsexual and make transgender an umbrella term for people who do not identify with the assigned sex.
However, people will disagree. It's a label that helps define people, for good or for bad.
I just go back to being Jennifer. I am a woman who corrected a birth defect.
