This Is What It's Like Filming A Hollywood Sex Scene

A video from the behind the scenes of the upcoming movie "Stretch" shows that it takes a lot of awkward, unsexy time on set to get a seamless, steamy scene on screen.

Costars Patrick Wilson and Brooklyn Decker readjust and make small talk while director Joe Carnahan offers insight into each characters' motivation and coaching: "Great fucking!" or "Do another one like that and we got it, I swear to God."

Actress Diane Farr described what it feels like doing a sex scene Esquire in 2005, and Vulture spoke to a few anonymous actresses and an actor a few years ago who shared their tales of bad simulated sex, real-life orgasms and just how unsexy it usually is. A common phrase uttered beforehand is: "Forgive me if I get an erection. And forgive me if I don't."
