Gosh, I guess it's all relative, isn't it? To me, anything along the lines of two years or less from start to finish is fast. I have three friends who fit that criterion. I thought I was the slow one.
I decided to explore the possibility of transitioning in January 2014. I had my first visit with a gender therapist the next month, I think. I started laser/electrolysis in July of 2014, and HRT in July of 2015. I started presenting part-time in public around April of 2016, went full-time a few months after that. I had FFS last September, and I am having SRS this month. If one arbitrarily considers SRS the "finish line", then it took me 3 1/2 years, and I still will get hair transplants, and probably a BA and a butt lift by next summer. I still have to finish my divorce as well. I'm not sure I could have done things any faster than I did. I voted "other". Transition is hell, and I can't imagine not wanting it done as quickly as possible, but when you are married with children and have a career, it's tough to balance needs versus wants.
With kindness,
Terri
