I personally don't care for watching people bump uglies in film. It's not explicit enough to arouse and I just don't see what the point is otherwise. I've always thought sex scenes in movies were just a way for the filmmaker to see a bitch naked, since their inclusion more often than not just pads out the runtime and serves no purpose to the narrative.

There are a million ways to tell the audience that two characters got down to business. Actually showing it is probably the least creative of them all.
