Looking for "Sex in the Air" in Chicago

My wife and I are flying to Chicago tomorrow to spend the weekend celebrating our anniversary. We always have fun when we travel together...just to get the chance to do things we can't do around the kids. We have a "no underwear" rule (which isn't hard for my wife who hardly ever wear underwear) and try to have sex in different places in whatever city it is.

While we are not swingers, we do go to Colette's in New Orleans on some special occasions. It is such a turn-on to watch other people having sex or to have sex right next to another couple or threesome or whatever. The sounds, the sights, it's like "sex is in the air".

My question: Are there any sex clubs in the Chicago area that are open to nudity, sex and alternative lifestyles? If not, are there any places that inspire a sexual atmosphere?
You can sign up for SLS.com (swinglifestyle.com) for free as a couple...just put your location as the zip you are planning to stay in....then look under EVENTS and it will give you a list of the most active clubs and groups as well as some private parties. They love travelers and I'm sure you will get a warm reception.
Have fun! A
Thanks, Alaiine, that's a great website. Unfortunately, it looks like this weekend there are no parties in Chicago. That's OK...we'll still find some fun.
Send me the zip for where you will be staying....In Dallas on any given weekend there are at least 40 or so parties on a Saturday night....and 10 or so full time lifestyle clubs running....you just gotta know where to look and who to ask....so to say there are no parties in Chicago is a laugh....I'll be HAPPY to find you some fun and contacts up there....you can pm or text me...Will you have a car up there?
