I was born September 24, 1956 but have now declared my new birthday as January 27 as this is the date to commemorate my correct gender. I was surprised that on Facebook they allow you to change your birthday up to three times while I figured unless you have done something along the lines of what I did you would get it right the first time. Some might have issues with changing one's birthday yet I don't. Along the same lines when I changed my gender marker and first name I changed my last name too as this (at least for me) was one more thing what had to be done to wash away my former identity.

Something for you to consider or not, changing one's last name might be right for you. The single downside when I did this was my login name at work did not change because after working there for 20+ years it would be a real chore to apply all my security settings. This is no different than a female married, takes the husbands last name, same applies so it's nothing to do with changing gender (way of topic).

Up side is I have two birthdays in 12 months woo-hoo.
