I am in the hospital with my wife of 10 years who has just gotten her gender reassignment surgery. AMA!
I met my wife u/thisisnotmyjob before she started her transition. She and I have been together for over 10 happy years and as of yesterday she finally feels complete. While we're in the hospital, I'd be happy to field any questions you may have about her transition, my experience being married to someone during their transition, or the gender reassigment surgery process itself. We have a lot of info to provide, and I don't mind answering NSFW questions if you've got them!
EDIT: Thank you everyone for your questions, support, and interest! And the gold! Wow, I had no idea this would get so popular. I'm getting really overwhelmed now with everything though, so I'm going to stop commenting. /u/thisisnotmyjob also would like to thank everyone and she's done too.
