First off, welcome to Susan's.

Be sure to look under the Announcements heading. There you will find the rules we live by in this little world of ours: "Site Terms of Service and Rules to Live By", "Standard Terms and Definitions", and "Post Ranks". Look through the other stuff there, too.
It certainly can be confusing to be transgendered or gender variant. You will want to build your base of knowledge of what it all means to you so that you can go forward. Conselling usually helps a lot - talking with someone who is trained to help us sort out all our confused feelings.
As Cynthia Lee said, this is a complex thing and you need information to help you decide what you want and need to do for yourself. There's plenty of good information here and lots of helpful people, so jump in and explore.
Happy exploring.
