Are you familiar with the swing clubs in Phoenix?  Unfortunately the best one closed down a few years ago and the ones that are left are ... well, let's just say ... suck! Vegas has the Red Rooster which is pretty good and SoCal has a couple of good ones.  But the Phoenix swing club scene is very lame.  The best bet is to go to a house party.  Barcelonas in Scottsdale is also pretty popular on a Saturday night with the lifestyle crowd.

Here is a link to some of the clubs and places to meet other swingers:

However like Jeffe suggested the best way is to go to a house parties where you would get invited by the house owner most of the time. I have founf that over time that Yahoo! Groups have many swingers and there are many that are located here in Phoenix. I would suggest that you sign up to one of those Groups and then see which one will work best for you. I used to belong to a club called Club Plzr and they had a monthly gathering at a hotel where most couples got a room for the night (usually a whole floor plan and you needed a seperate key to get up in the elevator to keep unwanted or uninvited guests out) and then they had on open bar at the ballroom and you mingled for a few hours and then continued up to the room. There were no closed doors and it was A LOT of fun. However since I haven't had a steady partner for a while I haven't attended one of those in a long time. But here is their website, however you have to apply to be part of their group and they do not say yes to everybody unfortunately, but it could be worth a try: http://www.clubplzr.com

I have on several occasions went to clubs as an escort and you don't have to be married or living together to go there, so 2 friends could easily go and have fun together. So I wouldn't feel awkward to go with an escort at all. It is all about having fun, right? But like Jeffe said, there are very few in town and the ones that are here aren't that good.

I hope this helped somewhat
