'Like a bag of leprechaun's gold'

Sex in the movies:

On most television productions, love scenes take between three and five hours to shoot. A love scene on a feature film can require a day or more of shooting, and it's not out of the question for people to be making coffee and serving food right next to your set. After each take, the makeup department not only does the usual touchups but it also typically sprays the actors down with a rosewater and glycerin concoction to make them appear sweaty. While women wear body stockings, G-strings, and pasties on-set, men get what is known as a "sock."

"It's a flesh-colored pouch that wraps your genitals up like a bag of leprechaun's gold," describes Sparks.
