This has been a great discussion. I echo what Steph said, I am an older TG (age 56) and I am doing this for me. I don't want to hurt anyone else, but then I have to consider this is the only life/body I have - no one else can be me.
I like to wear make-up, dress feminine, have nice hair, etc. For me I think it is because I denied myself these pleasures for so many years and I want to experience them with what little time I have left to live.
We each have our own path to follow, there is much we have in common, but we are each individuals with unique personaliities, likes and dislikes, etc.
I am just starting out on this journey and don't know how transition will go for me, it could be the best thing I have ever done or it could end up being something I am not expecting. I don't know. I am devoting myself to explore, learn, educate myself, seeking help and advise - and then go from there. It seems to me that transition means different things to different people, and I can't presume to judge someones else's decisions, heck I have conflicts with my own decisions.
