Hello, and to answer your 1st question, yes you are in the right place. We all have different backgrounds but if you have the question about your gender identity this place might yield up the answers. Now if you are this gender or that? That is with in you none of us can tell you we can only share experiences common or not. And by relation to them will understanding come. We will also help celibate understandings when you get them.😉
And by no is it too late, as the other girls mentioned. In fact on the positive side of studying later in life is you have a lot of life experience and wisdom to bounce the issues off of and it sounds like you have that in plenty. Those early bird girls might get there sooner in life but will have missed the life journey late bloomers get.
Take care and hope you find what you seek.
