There is a decent offer of striptease clubs in Barcelona. One of the most popular venues is Bagdad (http://www.bagdad.com/). The erotic shows are much more explicit than you would expect in a club situated in the touristic heart of the city on Carrer Nou de la Rambla, 10. It’s not only the regular striptease or lap dance or chicks grinding around a pole; in Bagdad be prepared to see also double-end dildo action, or live sex on a club scene. But be aware that this comes at a price: entrance fee is around €90 and count on much more for a VIP room treatment.
In a bit cheaper segment you can find clubs such as Doll House Barcelona (https://www.dollhousebarcelona.com/). This strip bar at Carrer de Sagués, 21 is also a popular place for bachelor and stag parties.
Just like is the case in France, swinger clubs are gaining popularity in Spain. Luxurious swinger clubs in Barcelona like the fairly new club Oops! Barcelona (https://www.oopsbarcelona.com/) on C/ Anglí, 69 offer great options for open-minded couples, who like to push boundaries.
When you would like to make some dance moves before entering into more hard-core action you should check out Disco Swinger Club 6&9 (http://www.6y9.com/) on Carre d'Alcolea, 58. Swinger clubs differ a lot as far as entrance policies are concerned. It is not always mandatory to bring a partner but some evenings or events might be open to couples only. Also as a single man you usually will need to pay a higher entrance fee.
