Hi @NatureLover 💜🌈
I don't think it's ever too late. I have/had the same attitude as you but I meet many transmen who transitioned late in life, well into the second half. It's an ongoing journey for me, I haven't come out to anyone apart from my psych. For me it's questioning gender & sexuality. I think we've all been socially conditioned in so many areas of our lives, I never knew there was a different possibility in life.
You could contact qlife.org.au or search Facebook? I found a great group there for the older generation, but it's 'not' for lesbians (I don't want to exclude you, it's just a closed group for transmen). There are also in person groups depending on where you live.
Stay in touch xoxo
