I don't know much about the culture specifically, but I'm reminded of the story about the Indonesian president whom the KGB tried to blackmail by taping him being seduced by two flight attendants.
> Before starting the blackmail, KGB invited Sukarno in a small private movie theatre and showed him the pornographic video, in which he was playing the main part. KGB agents were expecting him to get really frightened, that he would agree to cooperate with them at once, but everything happened vice versa: Sukarno fondly decided that it was a gift from the Soviet government, so he asked for more copies to take them back to Indonesia and show them in movie theatres. Sukarno said to flabbergasted agents that the people of Indonesia would be very proud of him, if they could see him doing the nasty with Russian girls.
It sounds like you have a specific, non-western culture in mind which finds it very easy to talk about about sex.
Which is it?
