Cici, I have been searching for answers like you to find the root on my obsessions sensual in nature and one I came across with a SARA test. Then for a fee I took a SAST Sexual Addition Screening Test and found it very informative for me. It was after this I decided to pursue gender counseling to see what part of my obsession was gender related. You might want to see if it may help. From what I know now, I am somewhere on the scale between M and F. I am very fortunate I am working with a gender specialist and meeting with a group of trans folks regularly. After doing endless searches on the net I dont think there is a "test". Perhaps you could find an therapist who will do Skype? Mine offers all methods but I prefer in person.
