I do too. After reading much of that, it seems to me true autogynophilia is very rare.
I see some autogynophilia happening as a stage of transitioning that most of us go through, and I think it has more to do with the taboo nature of women's clothing rather than any kind of actual sexual attraction.
When I was a child, I had sexual excitement from cross-dressing even before I had any sexual attraction to any person, and it continued over time. I noticed as I did it more frequently and publicly (like among friends who knew), any kind of excitement I got from it decreased, to the point it went away completely.
I realized that I wasn't getting excited by wearing women's clothing, I was getting excited by the threat of being discovered wearing women's clothing and the transgressive nature of the act. It's true that MTFs that used to feel excitement from cross dressing no longer tend to do so when cross dressing just becomes dressing, that's how it was for me and everyone I've come across. And this is before and regardless of any decrease in our testosterone, and therefore sexual desire in general.
The real problem with the Blanchard and his cohorts is that their biases come through loud and clear against us in the research and come to a completely wrong and dangerous conclusion. Sexual excitement from cross dressing is ultimately the byproduct, not the cause.
