Hey. Glad to hear from you. I just wanted to take a moment to give you a few more links that I have found. These have been helpful to me in my journey. I am no expert, but wish to pass along info I have found useful.
This site is by a bio-male who grew out to a c-cup. His main page
http://www.male-breast-enlargement.org/
has a few interesting articles, but is full of adverts.

HIs blog page plus the comments made by the visitors makes for interesting reading.

This site has a lot of thought provoking ideas and theory on the "sx" of the brain. How we think and act male or female. It does include a testing link.

This site also has a testing site developed by the site developer. \\The site itself has good info and a Q&A section. I had lost track of it but found it again recently.
