I think how young you know that you are trans will have a degree of impact.
If you grow up as a boy, have girlfriends, get a job and career that way, get married, raise kids as a father and reach a degree of social security a lot of that HAS to be filtered through life as a man.
Inevitably it will bring socialisation that can never be eradicated.
The effects of hormone changes drop in degree of change pretty exponentially after puberty and have minimal effect on someone transitioning in their 50s onward.
Physically the male body can never be very successfully changed post about 25. Socially much the same will probably apply.
Plus given how powerful I know the dysphoria was from primary school onwards I cannot conceive of the psychological damage to mental health and behaviour that deferring transition until decades after that would do.
Not to mention the selfishness of dragging spouses and children into your mess and not as a priority resolve that first without involving others.
And I do wonder how deep can be the dysphoria or if it ever really exists if you can put it aside for 50 years.
I know I could never have done that.
