The mere act of taking the test in itself shows more than a passing interest in how one identifies as one of the opposite sex. Unless pranking is counted as a legitimate answer. Sure, you would not want to make a final diagnosis or choice based on the results of it, but why would anyone not interested in their own sexual identity even contemplate the test? Any way, I enjoyed taking the test, don't give it too much shrift, found myself probable transgender, even though my renewed HRT is over 4 months now, and SRS is very far behind me now.
The fact that I never had any training as far as being a girl is concerned also played largely into my probability of being diagnosed as having GD, instead of being solidly Transexual. I never thought much about that before, but girls usually go thru training as to how to be a girl. Makeup, dressing, how to behave [including the stereotypical behavior assigned at birth]... And this training is usually administered by, surprise surprise, other girls/women who want the best for them.
Of course, I could be wrong...
