I found this article (http://en.wikipedia.org/wiki/Gender-neutral_pronoun) that gives all sorts of suggestions for describing people with different genders. (Look down at neologisms for the suggestions.) I personally like Spivak pronouns (http://en.wikipedia.org/wiki/Spivak_pronoun) (the article might not be accurate, but I like what it says anyway), but that's just my personal preference.

I hope you find something that you like. :)
