I go regularly to both Colette and 13th Floor. Colette is more of a night club and has a younger, higher end crowd. 13th floor is more like a house party and the people are more down to earth and a little older usually (great hot tub fun to be had). They are very different but I think both are a blast.
I go with a NSA firend that I have know for years so the following doesn't apply to me but I have seen it cause issues so I want to at least mention it: If you plan on taking an escort, make sure you discuss activites first.
Will she do girl on girl? usually yes but never know
Will she do full swap with other couples? some do and some don't
Will she do group?
Will she go to the after party?
And obviously what is the rate? we are normally there for 4 to 5 hours.
I also would have a few sessions before going to a swingers club but that is just me.
