Welcome, NA!
In some ways we are similar. I too had a very accepting family and they never forced me to be anything other than who I presented myself to be: Male ( AFAB). The main reason I didn't transition until now ( 47 years into my life), is because I had no idea that there was this option, plus, had I known, I would have been too scared to go through surgery especially, and without that surgery, there would have been no point in transitioning. Furthermore, I had adapted to presenting as male, which females can do so much more easily than males, because we can dress in male clothing or andorgynous clothes, and we can feel OK with that. That was the case for me, until now.
I have now reached the point that I need to transition because despite male type clothing, nobody ever mistakes me for a male anymore ( aging does that: boobs grow bigger because that's where a lot of the extra fat goes, and face softens even more, even though I'm very slender and carry little extra fat) . This is now beginning to become an insurmountable problem. I also feel secure in my career and am building up my own consultancy while still in employment. It's time to transition fully now.
So, there is always time to transition. The best time to do that is when you feel ready ( it may be never, it may be in 10 years).
Welcome aboard, and make yourself at home in this most accepting community on this planet.
