I chose my name with the thought in mind that there is no masculine form. For years, I was going with the feminised version of my boy name, but I knew too many Briannas already and wanted something more personal and not corruptible into anything icky. Thus, I had to give thought not only to my first name, but my middle name/initial AND my last name. How they flowed together, initials, possible meanings etc. Took me years ultimately, but I'm happy with my selection.
