Interesting.....I had SRS fairly early on in transition (only 14 months after going full-time) because I didn't think I'd ever have the money to pay for it again.
So there are other leftover problems that need sorting out. I still have a lot of facial hair that is white (I can get away with not shaving for two days, but no longer), a bit of a problem with my voice, and a brow ridge that demands bashing into a more feminine shape. More hormones and hard work will still be necessary if I am going to be completely passable.
Having it down there was always something I was conscious of, and I didn't really like to look down too much. I think when I get back home, its absence will give me more confidence in myself generally when dealing with other people. During my recovery from SRS I got to know people who had lived for years as women but still had a secret in their pants that caused them all sorts of trouble and distress. Even though hormones haven't done all they can to me yet, I'm so glad to have that thing out of the way.
Another benefit of surgery that no-one has mentioned yet is ID documents. Many countries allow these to be changed only after SRS.
