One of the first associations people have with arthouse films is that they get away with sexual things that either transgress the boundaries of bog standard cinema or show aspects of sexuality that can only be depicted within the arthouse medium. This is pretty much true and it all boils down to class prejudice and censorship. People who watch arthouse movies are thought to be more educated and of a higher social class. Therefore they can handle all the erotica, filth and perversion arthouse cinema can throw at them. Racy films such as Romance and Baise Moi get passed because they obviously wouldn't corrupt the middle class. Meanwhile 'low brow' films get censored to bits, in case they influence or inflame the rabble. Censorship has been done down these lines for decades. So thanks to the censors, if you want to watch a decent erotic film, you have to head to the arthouse on most occasions. This is where the truly daring and visionary erotic classics are to be found. If you are looking for porn, you won't find it here. These films have an erotic undercurrent and deal with sex as one of their main themes but they are stylistically accomplished and as far removed from 'Debbie Does Dallas' as it is possible to be.
