The sex scene was key in understanding Nite Owl's character. He's impotent without the costume, at least at first. He is the type of character who says he fights crime because someone has to, but it's really because it makes him feel alive and is arousing.
Dr. Manhattan is naked throughout because it shows how little he concerns himself with the rules of human society, except for when he's forced to do so.
All of these characters reflect the various reasons a human would really put on a costume to fight crime, and what would happen to them if they did. While they are close approximations to a line of characters that DC decided not to use in Watchmen, they are also analogs for Superman, Batman, etc. The purpose was to deconstruct superheroes and bring them down to a level that we all could relate to.
That may actually have been obvious to everyone who saw it--I've just had a few to drink and decided to get all philosophical in case anyone missed the point.
