A few more words that are related to sexual minorities:

Transgressive or Transgressively Gendered: Someone who does not identify as either male or female, but rather trangressive in gender performance. Neither Masculine or Feminine

Intersex: Someone with a mix of the two biological genders, usually does not identify as male or female

Guard Dyke: Slang term for a lesbian who is friends with and often goes out to gay bars with gay males. She often assumes the role of bodyguard against homophobes or unwanted advances for her friends.

Also, the difference between a fag hag and a fruit fly: a fruit fly desires sex with her gay male friend(s) whereas a fag hag is a female who has strictly platonic relationships with gay men.

A nice bunch of additions, those. Thanks for piping up.
