If Blue Is the Warmest Color has taught us anything, it’s that people sure are confused about lesbian sex. Let’s have a quick little crash course here. Slightly NSFW.

Blue Is The Warmest Color, a new French film about a young woman's first lesbian relationship, has caused a lot of controversy because of the prevalence of lesbian sex scenes.

In fact, this is what the author of the graphic novel, Leah Maroh, wrote about the scenes in the film:

Now, as a lesbian....
It was clear to me what was missing on the set: lesbians.
I don't know the sources of information for the director and the actresses (who are all straight, unless proven otherwise) and I was never consulted upstream. Maybe there was someone there to awkwardly imitate the possible positions with their hands, and/or to show them some porn of so-called "lesbians" (unfortunately it's hardly ever actually for a lesbian audience). Because—except for a few passages—this is all that it brings to my mind: a brutal and surgical display, exuberant and cold, of so-called lesbian sex, which turned into porn, and made me feel very ill at ease. Especially when, in the middle of a movie theater, everyone was giggling. The heteronormative laughed because they don't understand it and find the scene ridiculous. The gay and queer people laughed because it's not convincing, and found it ridiculous. And among the only people we didn't hear giggling were the potential guys too busy feasting their eyes on an incarnation of their fantasies on screen.
