This was in the paper the other day, and I've since seen it around town (seems to be part of a new AIDS prevention campaign). Of course something like this would freak a lot of people out in the States--especially if, God forbid, it received any public funding as I think it might have here--but my sense is that sexuality seems to be treated a bit more matter-of-factly here. (Incidentally, for some reason I find it amusing that the public health department here is called the Bundesamt für Gesundheit.)
