What to do i got wrong gender in my passport

For a US passport, go to the link below for directions on filling out form DS-5504. If you do it within one year of the passport issuance, there is no charge for the correction unless you request expedited service. You will need a copy of your passport photo.
Change or Correct Passport

If you have no time to wait for the corrected passport, and someone gives you a hard time about it, you can argue that the US government at its highest levels doesn't know what gender is anymore anyway. :)
