I agree with most of the comments here. I, too, found Keegan very annoying, and I just wanted him to shut up. Yap, yap, yap.
The binding sequences...sheesh, of course Ace bandages hurt. I wouldn't want viewers to get the wrong impression about binding, but I think they would from this documentary. That segment seemed pretty irresponsible. I was starting to get the impression that Keegan in particular really WANTED to suffer.
The lesbian perspective was understandable but also problematic. I do think that there's nothing wrong with the lesbian perspective as long as the filmmakers clarify their objectives--one of which was obviously to open up some kind of dialogue between lesbians and transmen. And I think the documentary should have noted much earlier (not in the last minute before the credits) that lots of transmen don't come from the lesbian world.
Overall, I'm glad I saw the film, and some good points were made. But it was a pretty ho-hum experience for me. At least I didn't blow four or five hours like I did with Transgeneration. For me, that doc was a REAL waste of time compared to the hour that I spent on Boy I Am (stupid title, I thought, but that's just me).
