In my trip now to the sunny Barcelona - Spain i found in the Ramblas area, the most popular street in the city where the tourist walking happily have , in front of the very famous market La Boqueria, you can find the Erotic Museum of Barcelona. A small Museum but very friendly, where you can take photos and videos, and have an amazing artistic collection of different cultures erotic art. A lot of movies, and curious objects . The ticket is just 10 euros and more then value of money. It is a really incredible trip to the erotism world. Go there !
