Le Mask

Le Mask is a well-known libertine and swinger club in Paris, conveniently located in the 2nd arrondissement. The club is exclusively reserved for couples, although singles are allowed on certain occasions (see the website). As its name suggests, the club strongly recommends visitors to wear a mask. Although this is not obligatory and you won't be sent home if you don't wear one, it's part of the club's atmosphere and overall experience.
