It is one thing to ask whether dead bodies should be plastinated and dissected to various levels and posed and displayed for the public and another to ask whether the parts to be displayed and the poses can be sexual. But...
The way a plastinate is exhibited can vary from country to country to reflect local sensibilities. A vote of local employees decided that one of the copulating female cadavers should wear fewer clothes in Zurich than was the case in Berlin.... it is quite another matter to conform the display to local preferences and prejudices that require different degrees of exposure for the male and the female and restrictions about different kinds of sexual activity. Just because something is a "delicate subject" doesn't mean you have to track local taste — especially when your whole enterprise challenges convention.
"Switzerland is the first country that already said from the outset that we could show whatever we wanted," said [Gunther] von Hagens.
"Zurich is ready ... but it's maybe not so easy in every other town," he said. "We have discussed whether it is proper to show homosexuality and in what way. This is a very delicate subject."
