In every movie that Jessica Alba is in, everyone always wants to see a Jessica Alba sex scene. A lot of the movies that she is in imply that she is having sex, but you never see her naked. In fact, in the movie Good Luck Chuck, you see her almost naked rolling around the bed with Dane Cook. However, you don't actually see her naked. Even so, some people still call this a sex scene.
Just for a part of a movie to be called a Jessica Alba sex scene, does not mean that she has to be naked in the scene. All that it requires is for her to be simulating intercourse with a male or female on the screen. In almost every movie that she is in, you get to see at least one scene like this. That is because Hollywood knows that sex sells, and that is a fact of life that people can not lie about.
