Biologically, there's three. There's male, female, and intersex. I'm not sure what- I'm pretty sure that's what it's called. Don't quote me on that though. Gender identities, however, there's like multiple, I guess, which I don't really support coming from like a queer person. Like non-binary is fine, but like all the other ones are just weird as fuck. But yeah, biologically, there are uh, three. So if you want to use science.
