I think that the ultimate taboo to some extent is sadism even more than masochism. If you tell someone that you like getting tied up or spanked, thats hardly big news in a country where gay people can get married where half the population lives but it definitely takes some trust to tell someone that you like or love them (or merely find them attractive) and you also want to hear them scream or make them cry. Or that you may be their knight in shining armor in real life but in the bedroom you prefer to be their villainous captor.

Maybe I just like pushing buttons and the most fun buttons to push are on a pretty girl.
