Human Sexuality as Explained by Nerdfighters

So my little sister is REALLY into these YouTube bloggers called the Nerd Fighters. I've only seen a couple of their videos, but this one came to my attention today and I thought I'd share it!

We talked about this model a lot in my Gender and Society class; there are actually theorists who prefer not to look at sex as a binary biological category at all, because there is a lot of potential diversity, and the way that we understand sex is mediated by society, so it's socially constructed. So the whole "sex = biology, gender = society" model isn't perfect. But I do think it's a really useful way to start people thinking about sex and gender in more complicated ways, and this video covers all the possible variety involved therein pretty well I think!
