There are gay pubs, bikers pubs, goths pubs..why not swingers pubs. Where people could meet in a munch type environment...we could develop signals as the Gay community to indicate our preferences...Couples only, single girls/men only, soft swing, etc
Mind you..I bet they would be full of more single males than a Gay Club!!!  
      How about some sort of badge or  ring or some thing like that!! that denotes you are a swinger, or a secret hand shake  
      isn't it hanky in left back pocket = top
hanky in right back pocket = bottom
no hanky = switch
I think that's right but not 100% sure  
      Woah, it's scary the stuff you can find with Google.
   
      Well, I dunno about the various gay haunts within the towns etc, but don't walk around a gay cruising/dogging site with your hands in your pants pockets.
You HAVE been warned  ! ! ! !  
      Funny about "young" lads, we had 3 in the layby a week ago  being a right nuisance.
Shouts of "is it gay night tonight then" and driving up and down...very gobby, until a tv went and talked to them.
Exit.
Fast.  
      So why dont we start a signal ....
Any suggestions??
It would need to be suitable for both men and women..
need to reflect preferences, ie Couples only, men only, ladies only, 
I suggest a password on introduction..like "Did I meet you at Mark and Helen Heaven's". A positive response would confirm. and need to say Munch rules apply!
So shall we start something???  
      Surely off white for men that masturbate??
