I have lurked on and off for years at this site, but finally registered an account today because I have something to say. Please listen to me.
I am trans. I also have something called Klinefelter Syndrome: that is, I have forty-seven chromosomes instead of forty-six. I have three sex chromosomes: XXY. This is actually a not uncommon event; it has the same stastical likelyhood as Down Syndrome because the mechanism is the same, just acting on a different chromosome.
People with KS are raised as boys, and the majority are happy that way. A significant fraction of us, however, are not. I am one of them.
