Here is what each means. I had never heard of IAS+
Sexual Orientation & Gender Orientation
Sexual orientation is who you go to bed with; gender orientation is who you go to bed as. These are independent terms. A comprehensive list of Sexual Orientations can be found
here.
Transgender
is a gender identity that does not correspond with the gender assigned at birth.
Cisgender
is a gender identity that does correspond with the gender assigned at birth.
Intersex
means you’re born with biological traits that are outside the strict male/female gender binary (such as anatomy, chromosomes, and/or hormones). Examples include Turners Syndrome, Androgen Insensitivity Syndrome, and Klinefelters Syndrome. Being intersex is not the same thing as being transgender.
Non-binary
typically is descriptive of someone whose gender identity is not exclusively male or female.
Genderqueer
typically is outside of, in-between, or fluctuating between the binary gender categories of male and female. Gender queer relates to the spectrum of both Gender Identity as well as Gender Expression - that is, they may move fluidly between the identities of male and female and separately may move fluidly between masculine expression and feminine expression.
Two-Spirit
refers to Indigenous people who express their gender or sexual identities as different from others. Not all Indigenous individuals who are not Cisgender or Heterosexual will identify as Two-Spirited, but all Two-spirit individuals identify as Indigenous. Some nations hold space for more than 2 genders, such as the Díne, The Anishnaabe, and the Lakota.
