For me, it would be more important than SRS.
Face it girls (sorry), your face is the first thing society sees. The SRS only addresses something polite society should *never* see.

If it weren't for the fact that you need SRS to get your primary documentation changed I wouldn't do it. Or at least only if I ended up in a relationship that I felt would be made stronger by giving me the ability to have intercourse with the proper equipment.
I want society to accept me as the woman I know I am. FFS would help that. SRS, for me, only confirms my belief.
And to my mind, were society more sanely put together, FFS would be the operation(s) to require two letters and RLT.
The way it is now you can look as feminine as you want and all you need is your checkbook. The FFS surgeries are as just as irreversible as SRS. Yet one minor corrective surgery between the legs and you have to ask permission of gatekeepers who probably haven't experienced the anguish we have. You must say the proper words and pass the proper tests because they, the males who have the power and skill, couldn't concieve of anyone wanting to mutilate their genitalia. So anyone who does wants to is obviously deranged and needs to prove that they really, Really, REALLY want to!
Sorry ladies, I'll get off that soapbox now. This is obviously something that everyone has heard before or thought it themselves, but every now and then I need to vent...
