If, like most visitors, you arrived at the Central Station and walked down the crowded Damrak you no doubt noticed the Venus Temple, which is a bit tacky but also a classic Amsterdam attraction on four floors and a bargain at only €4. You can take a look at ancient erotic woodcarvings from Indian temples, scrimshaw dildos and 18th-century silk paintings of sexual acts from China and Japan. You’ll also see mannequins of flashers and prostitutes, old porno films and some provocative black and white photographs, including a 100-year-old image of a woman with a gas mask, strap-on and whip that proves that the human race has always been perverted.
