It seems like there are many ways to meet other couples. We have tried the Local Discreet Affairs site, swing clubs and more recently private parties. It seems like the private parties are a great way to go. We have found the quality of folks is very good and most if not all are not pushy.
We even like to meet out of town couples at their hotels for drinks and see where that goes. We don't waste other couples time. We know what we like and want so we like to be upfront about it. It seems like that is the best way to have good time with other couples.
Its hard some times to hook up with all of the other stuff we have to do in your daily grind. So its a real bummer when you plan on hooking up with another couple and they don't show.
