Le Musée de l'Érotisme — the Museum of Eroticism
The Musée de l'Érotisme is a bit of a tourist trap, but hey, you're a tourist; it's okay to get trapped, and this place is really pretty fun if you're into weird stuff. Located on the main drag in Pigalle, Paris' risqué red light district, the Musée de l'Érotisme occupies several floors of a small building and spans several centuries of erotic art, ranging from the primitive to the tasteful to the vulgar to the downright hilarious. The museum doesn't take itself too seriously at all and it really is a fun way to kill an hour.
Looking through my pics from the museum, this lady-shaped guitar is the only one that I feel comfortable sharing on this website, heh.
One great thing about this museum is that it's open late; last I checked it was open 'til 2am, seven days a week. Be sure to confirm their hours and check prices on the museum's website.
