Third gender can be a bit confusing. I found it hard when I began learning about the spectrum. Third gender does not indicate that there is a third binary-gender, but that people identify out of the both the rigid binary genders, and the gender identites that exist under the trans*/genderqueer umbrella.

If I were someone who was third gender; I would not be male or female. I would not identify as masculine or feminine but instead, use these terms to explain how I am.

I do need to do more research on this one; give me 20 minutes or so and I'll find some links!
