Comedian Dane Cook has yet to master the art of onscreen lovemaking - because the steamy shoots remind him of his years as an awkward teenager.
Cook has co-starred in a string of bedroom scenes alongside Hollywood beauties including Jessica Alba and Kate Hudson, but the funnyman admits he reverts to a fumbling teen as soon as the cameras start rolling.
He says, "I'm much more introverted and shy, contrary to popular belief... You tend to go back to how you felt when you were in high school.
"Even though you're professional actors, you come to those scenes wondering things like: Are you going to be mad if I kiss you? Do I put my hands on the small of your back or can I go lower? Is that too low? Can you draw a map of where I can touch you?"
