I gave up after about 20 questions (question #20 was "feminine", which also rather threw me! - I answered "neutral"), because I kept having to answer "neutral", either because I simply didn't understand the question, or because I could give both of the two possible extreme answers simultaneously.
I'm still not very clear about the whole Aspie/NT thing (I'm slowly soaking it up, trying to form an intuition), but I felt the whole test (or what I bothered to read of it) was from a rather NT perspective. I would be quite surprised to learn that a lot of Aspies could answer these questions without having the kind of difficulty I had. Specifically, a lot of the questions seemed to be asking you to judge your own character as if from a generalised other person's perspective, and this is a real stretch for me.
OK, having got that off my chest, I pressed on to the end (like a man!):
Masculine 20/100
Feminine 61.7/100
Androgynous/neutral 38.3/100 [What does that mean? Is it just a coincidence that Feminine + Androgynous = 100, exactly?]
So, according to the test (which I take with a pinch of salt), I'm even less masculine than I thought, and a little bit more feminine than I thought. Overall, according to the classification given in the OP, I come out as "undifferentiated", which is what I expected, although this ignores my exceptionally low score for masculinity. I'm male, by the way, and for a long time I have wished I were female (although when I was growing up, I just wanted to have no sex organs at all, and to wear girls' clothes).

Almost certainly not Aspie, but certainly something like it
