I totally agree with you on the sex scene. I actually have a funny story about it (well its funny to me.)
Well my friend was on a flight to Europe, and Factory Girl was one of the movie choices you could pick for your tv. So she picked that, not knowing of the explicit content. I should also note that this was a class trip so she wasn't alone. So she's watching the movie right, and then comes the sex scene, immiediatly she's like omg. Two english ladies we sitting right next to her, and were staring at her, she felt super emmbarrased. Then one of her friends behind her comes up to her and says "Hey, whatcha watchin there?" So when then when the flight was over and people were getting off the plane, another friend came up to her and said "Enjoy your p*rn?"
Hahaha
