i'll ask a question i have my own opinion about; maybe it will open up an interesting dialog.
Sex vs Gender: to me there is a vast difference in these words, however close they may be in the english language.
sex is completely physical based (XX, XY, and all the various combinations).
as far as i'm concerned, there are 8 billion people on the planet therefore there are 8 billion genders.
Carley Simon, thanks for writing that song about me!
