Sulu was a flamboyant swashbuckler, but nothing in either the performance or the text indicated that he was gay. I just needed a pithy descriptor for my reductive comedy routine. I am open to suggestions.

PS: even the new gay Sulu is not necessarily all the way gay. He may be bisexual. I would not put being bisexual past the original Sulu. I feel like he could have gotten into any kind of pants he wanted.
