I'm attending my first swingers party this weekend with a FWB. I really have no idea what to expect. I know there's a buffet dinner, a dance floor, an indoor pool, and it's BYOB. I don't know how the actual "partying" gets started. Does someone yell, "OK everyone - go for it!"? Do clothes just come flying off, and everyone walks around naked? For that matter, what do people wear to these things? How do you approach someone that you'd like to have fun with? If it's just like a bar, then I'm out of luck because I was always clumsy in that environment. Do women approach men, or do the men always initiate the action? Also, I'm 60. will everyone be younger than me? Is there any chance a younger chick would ask me to have fun? Are people having sex out in the open, or does everyone go off to little rooms somewhere? I search for "swingers clubs" in sites like Pornhub, but that's all staged Czech sites or Dixie Trailer Park stuff.
Sorry for sounding so naive, but I just don't know what to expect. If worse comes to worse, I'll go there and have sex with my FWB, but we don't have to go to a swingers club for that. ANY PERSPECTIVE OR ADVICE FROM SOMEONE WHO'S EXPERIENCED WOULD BE APPRECIATED.

Last few of these I went to, it was helpful to be as charming and pleasant as possible ESPECIALLY to your hostess, or whomever's in charge.  
You might give some thought to approaching couples as a couple, especially if your FWB is good trading material.  
Don't push, let it happen.  
Worst case is that you go home with someone you already like and talk about all the hot people you saw at the party.

Have fun, and best of luck!

You are the man.

I've always been curious to try one, but have never found a girl who could introduce me to the scene.  

Someday, perhaps.

Are you going to a swinger party or a swinger club?  If its a party, how did you get invited?  I would talk to that person about what the "rules" are.  Also, go to SLS.com and check out the forums, there are lots of answers there.  As to rules, EVERY couple has them and they are all different, so its a tad difficult for a newbie to navigate.  Also, does your FWB frequent the lifestyle?  If so, just follow her lead.  

I have been to parties where its more low key and to those that have been wide open.  Fucking and sucking everwhere you look.  Clubs tend to be more wide open.  

Consider yourself lucky to attend at your age.  I am 64 and find it a tad harder to play at parties, etc.  Clubs are easier.  For me anyway.

I wish I could find a SB that would play in the lifestyle.

I appreciate the comments. My FWB - who I've only known for a few weeks, but REALLY like - has been to this particular party before, so I guess I'll just need to follow my lead. She's been a bit mysterious about it, responding to my questions with vague answers like "you'll see" or "you'll be fine", etc.  While not knowing just what to expect is, I guess, part of the thrill, I'm someone who prefers to know going in. I'll check out sls.com, although I'm not a big fan of having to register on the site.

Better hunting on LifestyleLounge.com - there's a little bit of curating going on behind the scenes (mostly to make sure people are real), and a lot of supporting material about etiquette and forums and stuff. I'd prefer that place to SLS. Give it a look.

all you need is a handle and an email....
