In her book of essays, Not That Kind of Girl, out today, Lena Dunham writes about what it's like to shoot sex scenes — and she's honest about it, unlike most actors.

Professional actors always give canned answers like "It's just a job, it's so mechanical" or "He was so fun to work with, he felt like a brother"...

But, actually?

It's fucking weird. Yes, it's just a job, but most people's jobs don't consist of slamming your vagina against the flaccid, nylon wrapped penis of a guy wearing massive amounts of foundation to conceal his assne. I've suffered humiliations such as kneeing my scene partner in the balls, realizing under the bright studio lights that there is a thick black hair growing out of my nipple, and finding a lubricated prop condom stuck between my butt cheeks seven hours after arriving home.

The truth is out, and it's wonderfully awful. (Assne.)
