AMA #1 -- What's your definition of "tranny," crossdressing?

This is the first question for a new series called "Ask Me Anything" starting with this post.  I have collected a number of questions frequently and not-so-frequently asked of people in the transgender community.  My answers are MY answers and unless I state otherwise, only from me.  Please send me any questions that you think I should answer either in Comments or via email.  Let's begin!

Ask Me Anything #1

What's your definition of "tranny," crossdressing?

For the first question and answer for AMA, here are my definitions of various terms that I use in this blog.  NOTE: These definitions may not be the same as yours.  I am not saying that my definitions are right and all others are wrong.  I post my definitions so that you can understand how I am communicating.

• MtF -- Male to Female -- This indicates the direction of someone changing their appearance, body, or way of life.  
• FtM -- Female to Male -- This indicates the direction of someone changing their appearance, body, or way of life.  
• MtT -- This is a recent term indicating a man changing to a transgender person.  This is used to reflect the reality that a male cannot become a female due to his DNA.
• Crossdresser (CD) -- A man who wears women's clothes, makeup, and accessories to appear like a woman.
• Transvestite (TV)  -- There are multiple definitions for this term.  It is often used in Britain to mean the same as crossdresser.  In the US, this term is used to describe crossdressing for sexual purposes or as a fetish. (Slang: "tranny")
• Transgender (TG) -- This term has many definitions.  Many years ago "transgender" was used as an umbrella term for anyone who is "trans-".  Because this definition was somewhat vague, over time this definition has been refined.  Today, sometimes "transgender" is used instead of "transsexual".
• Transgender Woman -- MtF or MtT -- A person born male, identifying, appearing or living as a woman.
• Transgender Man -- FtM or FtT -- A person born female, identifying, appearing or living as a man.
• Transsexual (TS) -- A person who is changing their sex using hormones and surgery. Additional terms include:
• Pre-op Transsexual -- Indicates that SRS/GRS has not yet been performed.  
• Post-op Transsexual -- Indicates that SRS/GRS has been performed.
• Non-op Transsexual -- Indicates that SRS/GRS will not performed due to any number of reasons.

• Intersex -- People who were born with a problem with their genitals due to irregular chromosomes.  Often, surgery is required immediately after birth to prevent fatal complications.  Even though this term has been replaced in the medical community that describes the condition better.  Intersex should not be confused with gender identity. However, there may be gender identity issues with people who are intersex.

There are many other terms not listed here.  Facebook users can choose from 50+ different gender and sexual identities.  There isn't one term that I know of to describe all the people in all of the above definitions.  I have seen some people use "T*" or "Trans*" but I don't think these are used universally.

One thing I have found interesting about gender identity (not including Intersex) is that a person has flexibility in which term to use to describe themselves.  There is no blood test, x-ray, MRI, etc. to determine one's gender identity.  A person can use whatever term best fits how they see their gender identity.  Note that these terms are not rigid and restrictive.  A person may describe himself as a crossdresser, then maybe as transgender, and then maybe transsexual.  There is no defined path or progression between these terms.  Also, only one term, crossdress, can be used as a noun or a verb.  The other terms should not and cannot be used as a verb.

Many years ago, crossdressing or transvestism was illegal because society and the legal system linked it to homosexuality.  The predominate point-of-view was that the ONLY reason why a man would dress as a woman would be to attract a homosexual for sexual purposes.  Today, for the most part, gender identity (transgender) and gender presentation (crossdressing) has been unhooked from sexual identity (heterosexual/homosexual).  In my opinion, "transgender" is slowly replacing "transsexual" in order to remove any sexual connotation for changing one's gender.  

Finally, there has been a lot of controversy about gender identity questioning if it is a physical condition, mental condition, or none of the above.  This is a topic that will be discussed in another AMA post.
