There are two museums on Barcelona's Ramblas: The Wax Musem and the Erotic Museum.
Barcelona Erotic Museum Yes, the obligatory sex museum, for those stag/hen parties and randy couples who've gotten tired of being all romantic.
It's an erotic museum, so you know what you're getting yourself in for - if you've actually made the decision to enter such a museum, you're not likely to be very offended by what you see.
Having said that, I was surprised to see old black and white pictures of what were clearly nude underage girls. But they were so small that no-one is likely to get their kicks out of them. Instead, they are an interesting insight into the history of erotica.
