Sex and Zen (1991) – Hong Kong
No erotic Asian list would be complete without this Hong Kong erotic cinema milestone which eventually spawned numerous sequels including a blockbuster 3D rendition in 2011. Sex and Zen is a softcore sex comedy that in certain parts of the movie almost border on oddity. The story revolves around a Ming Dynasty scholar's lust and sexual rampage. It shares the same 'penile mutilation' as In The Realm of the Senses but not on a serious note, rather as part of it's outlandish humour. One of its memorable scenes, which is actually the most unerotic part of the film, is when the protagonist has a horse's genitalia surgically grafted onto his body. From this, his erotic sexual exploits begin. One thing to note, you will never look at flutes the same way again.
