I also ask these questions as a man who has a pair of pink hair straighteners, "emergency moisturiser" in my car and office and who spends a huge amount of his spare time watching oiled up men pretend to fight each other. And there have been plenty of times I've taken stick for all three of those things. So y'know.
I also think that this kind of does matter to Nakamura's presentation, especially if he's going to be booked by the man who created Adorable Adrian Adonis, The Genius and Goldust. Nakamura is clearly playing with gender expectations in interesting ways.
Just think people are too quick sometimes to jump to defensive positions, and no good comes of it. And I don't think it's an irrelevant question either because if he WAS gay, it would be a huge deal. It's still something wrestling hasn't really addressed properly, beyond Pat Patterson on the reality show really.
