Gender isn't sex, and people can claim any gender they want. I believe there are hundreds of them nowadays. But with sex, almost everyone is either unambiguously male or unambiguously female, and intersex conditions are close to a rounding error, statistically. Also, trans has nothing to do with intersex, so mixing up all that X and Y stuff into this discussion doesn't really help.
