. . . I am technically legally "male" for marriage, or anything else where the birth certificate assignment of sex is used. Great, as a lesbian I married my wife legally without having to drive a couple miles to Greenwich CT. On the other hand, I am female on my driver's license, because the standard for DMV is a letter from a medical or mantal health professional certifying as to predominant gender. The driver's license is commonly used form most purposes for proof of identity, including sex.
Federally, I would be male for passport purposes were I to apply for one, unless I wanted a special passport good for one year, for use to have surgery in another country. Then again, I am female for social security purposes, having changed my name and sex under social security regulations in effect before October 2002.
I have a court case pending in New York Supreme Court, New York County, challenging the birth certificate designation on the basis that the initial designation as male was erroneous. This may result in my marriage being voided - which would just put me in the same legal position as any other lesbian in New York, rather than as one with a "minor technicality."
