Genderqueer? Someone who is genderqueer does not identify as male or female, but instead as neither, both or somewhere in between. They do not believe in a gender binary (the idea that everyone is either male or female). Some people who identify as genderqueer also identify as transgender.
Intersex? A person who is intersex was not born clearly identifiable as male or female. This is because his or her genitalia, chromosomes and/or secondary sex characteristics do not exclusively belong to one gender, but instead are some combination of the two. In Western culture, babies who are born intersex are often given operations to make it "easier" for them to live as one sex or the other.
A she-male? She-male is a term used to refer to a pre-op male-to-female transsexual who has a penis, but otherwise looks like a woman (often with the help of hormone therapy). This term is typically only used in the porn industry and can be seen as insulting or derogatory.
