For sexuality though, I'm an asexual aromantic, which has made writing a little interesting as writing romance scenes feels really strange to me. I've wound up just finding excuses to keep my characters as children for unnaturally long periods of time in order to just not include that stuff for a while.
As for my gender, I'm old enough to have been around in the days where we practiced proper internet safety and didn't share that stuff. Probably fine now, but I still find it a little amusing to simply not share it.
