He has said over and over that he's a man though, and explained away his plastic surgeries, saying they have nothing to do with his gender orientation. I'm not saying there aren't (kind of obvious?) signs to the contrary, but until he says otherwise, I think we should believe him. All people should have a right to experiment with gender if they feel like it, and maybe that's all he has been doing.
If he does ever say he's trans, then yeah, open arms and stuff. But I do have to say turning your early transition into a reality show circus (ahem, documentary) makes me nervous and seems crass, so i kind of hope it isn't going there.
