I was thinking of not revealing my MC's gender/sex in a short I'm working on. It's in 1st person, so I'm contemplating keeping even the character's name from the reader, but that's not such a big deal because it's a unisex name. The character is completely alone through the entire short (or, rather, doesn't encounter other sentient beings), so I don't have to worry about social situations, and the MC's looks and outfit are very androgynous too, so even stuff like mirrors etc. aren't a problem in keeping the sex a secret without any extra effort. So, can you relate to a character you don't know much about? Is it necessary to e.g. know the character's sex? I've been told by some people that they have a hard time relating to characters of the opposite sex whereas a couple were downright annoyed by the notion of not knowing the MC's sex. Personally, I've never had any trouble relating to a character of the opposite sex. Even when I was something like 7-8yo, one of my all-time favorite playable video game characters was kinda like this: I didn't know her sex or even that she was human. It was only revealed in the very end but only if you beat the game fast enough. All I knew was that it was a kickass character, and that didn't change when I finally did find out she was human and female. Now, video games are a different medium, and I don't think I've ever read a book where I didn't know the MC's sex, so I'm wondering if it's generally considered "necessary information" for a good story? I mean, especially considering some of the people who have opposed the idea, but I kinda like the premise of focusing fully on the character's actions, showing who the character is solely through behavior, choices, opinions etc. instead of what the character is/what's in the pants. Anyhoo, what say you?
