The Twilight Saga: Breaking Dawn – Part 1 - (2011)

Having to read about the sex scene between Edward and Bella in the Twilight series was awkward enough as it is, but was even more uncomfortable watching it in the movie adaptation.

There is a scene which shows Bella (Kristen Stewart) losing her virginity on her wedding night to her vampire spouse Edward Cullen (Robert Pattinson).

Kristen felt pressure to shoot the scene in which her character Bella conceives a baby.

She said: "In the end, I didn't feel like we had filmed a sex scene, because we were both so uncomfortable and insecure, and because it's something very subjective.

"There's times when there's weird close-ups, and everybody has such high expectations for these scenes."
