Speaking for myself...
How has my transition changed my life? In one word happiness.
I understand that for cisgender male and female it might be difficult to understand why one would transition and, when possible, even change their penis into a vulva or have a penis created. After all that's your "happy" pleasure private part. Well simple... I wasn't happy with my penis. Yes... I needed my penis to have an orgasm, and have 4 children, but other than that I didn't like the way it looks on me.
And I don't just mean the looks. It didn't belong their in my feelings. I was afraid of my penis in childhood. I always thought it will "fall off" or something after having sex. I had no sexual education and I was raised very strict reformed Christian. (Which i am not, after I reached my 16th year, I was allowed by my parents to step out)
I did have female behaviour and expressions, until being bullied at a young age, locked it up.
When I started to transition I thought the effect of hormones and blockers will be enough to soften the mental discomfort, but as my body progressed in femininity, the "partly disabled" penis became an even bigger issue. Especially in the shower and mirror.
Now after surgery I have zero discomfort with my body, glad I no longer have this penis and equally happy to have a vulva.
Next to the physical change (that no one sees on the outside), it clearly affect my happiness and that shows in my expression and self well being. (Looking for a different word, but my lack of English is not helping)
On social life my relationship with my wife and children has progressed significantly. Years ago my wife and I where in court to get divorced, but we ended the procedure as the law changed, and decided to stay legally separated.
Now my wife and I are best friends, after I started to transition. We are getting back together again and my wife stayed with me the entire time during my surgery, bedside in my hospital room, even though i rented a hotel room, she choose to be with and near me. She also helped me during recovery.
I think she noticed my behavior and happiness after no longer being a terrible male.
I do understand that I am a woman of trans experience and I know where I came from, I will never be as "complete" as a cisgender woman, but I do feel complete and happy.
Also for the record, I paid for my transition surgery myself, so "taxpayers can't say they paid for me".
Thx for asking and reading my honest reply.
I am open and out, obviously, and always telling the truth.
I like to add that most of the time people only talk about transgender woman, not so much trans man. That's most likely because it's nearly impossible to remove certain masculine features through hormones and surgery, for example the bones and body height.
This is true for trans woman who transition after puberty and later in life. I started in 2015. Now those who start before puberty, or who are on puberty blockers, will have a much better results and are most likely not going to be recognized as trans.
Trans man on the other hand will change quickly into the masculine features that after 6 to 8 months that will make them not recognize as ever been born as female. Unfortunately for the trans man, surgery is a much more complicated and expensive option.
Our bodies start out the same, in the first 7 weeks in the mothers womb we are all female. That's why it's easier to transition from male to female genitals
