It's not that I pay a lot of attention to sex scenes. The problem is American movies are overloaded with sex scenes or innuendos, violence, etc.
If I'm watching a movie like Exotica or any moving involving love/sex, I expect sex scenes, but the amount of sex in movies is ridiculous.
Maybe it's just me, but there is no reason to have sex in ALL movies. It's just to get more ppl to watch their dumb movie. It seems that even the movie makers know their films suck which is why they throw in the sex scene. Nothing wrong about sex, it's natural but a sex scene does not make the movie - in some cases, it cheapens it.

Perfect example: Titanic. Maybe if the director had spent more time on the historical aspect, rather than steaming up the car, the movie would have been a lot better. True, it made a lot of $$$, but I would not see it again. When the ship finally struck, it was like watching Niagara falls. The Poseidon Adventure was a lot better.
