why put down on someone else's fantasies.

In fact the Japanese use a type of nose "hook" for bondage and S&M, if you think it's funny try being bonded helpless and have one hooked up into your nose and see how "easy" it is to resist the pull of it.

Also the japanese have special herb mixtures which are so potent that the smallest touch from a cotton swab covered in such mixture will put someone into very strange mental states and/or unpleaseant states such as useful in S&M.
