Our next monthly bi-swinger party in London is on August 7th. I hope to see some of the couples and single bi-males drive in for it.  It is the 11th year of hosting on-premise sex parties.  3 playrooms, a fetish room, living room, kitchen counter and outdoor patio with under the stars. http://bi-swinger.com has over 100 pages of information.  All clothes are left at the door and single bi-males welcome.  Very much group  and hands on play.
