Ever see Taking Lives (you really don't have to BTW), its not what could be called good, but there is an lengthy Angelina Jolie-Hawke sex scene. She got her kit off (I mean, gosh DAMN) while the Ethester stayed fully clothed, it was very bizzare and at least partially, killed the hawtness of the scene.
Not that I wanted to see Ethan Hawke's Christian-Bale-in-The-Machinist-type-body, but if you can't convincingly make love to one of the most beautiful actresses on earth, how hard must regular acting be?
