I identify as a male because that's my biological sex and it helps medical professionals when diagnosing or prescribing for me. Other than that, I just do what I want, wear what I want, and it would give me quite a chuckle if I made a "man's man" question his sexuality, just like Ueda has done here. The joke isn't on Ueda or the others crossdressing. It's on our man's man Tozawa, who will now spend the rest of the series flailing helplessly as his idea of sexuality is broken down and restructured. I love this series so far.
