Can someone name some genders and explain to me what each one means?

People are complicated and have so many ways of identifying themselves.
It's more complex than this ... but this is the easy way to look at it

There’s 2.. pick one

Male have penises females have vaginas

It's one of those things you either understand or don't. Don't think too hard about it and just let people be weird.

Just accept all regardless of any labels attached to them. There are many sites on the internet that beak down ,in great detail, what the specific genders are. Start there. Not lists, explanations. Essentially your sex is below the waist, what reproductive organs you have, and gender is above. Gender is how you feel and relate in the world. It may be the same as your sex- or not.
