As a rule I don't like most of the erotic Category 3 (sort of like the NC17 rating in the US) films that I've seen from Hong Kong. They tend to be neither particularly erotic nor particularly involving (I won't even mention that they tend not to be remotely funny when they are also comedies). To that end I was rather surprised to find that The Forbidden Legend: Sex & Chopsticks is both good and erotic. The thread bare story has the son of the court sexologist telling his story about learning about sex and then going forth into the world with an angle towards his wedding. For much of the film, say the first half, the film is both sexy and involving. High art its not, but as an erotic romp about a young man sewing his oats its very much entertaining (and the scenery, both male and female isn't hard on the eyes either). The films flaw is that at a certain point the film loses steam. Any real semblance of a plot pretty much disappears and we are left with some amusing sex scenes but not much else. The film goes from entertaining to a bit tedious, and I found myself fast forwarding through the sex (I think the problem is that the couplings in the second half, with the exception of the final sequence are rather dull). When I reached the end I found that I still liked the film but not as much as at the start. To that end I recommend the film for those adults looking for an erotic change of pace, with the warning that you'll probably start to lose interest in the sex as the film progresses.
