There is one 'club' that I know of, called FetFest Playspace, on Calvert St. Just opened up about a month ago. There used to be Baltimore Playhouse, located on the same street, but sadly, it burnt down a few weeks ago They were and still are in the process of securing a new location.

Joining Fetlife will give you the inside scoop on all of the kinky, local 'happenings' in the area. There are a couple of clubs in DC as well.

Good luck!!!
