I haven't been to a Phoenix M&G in years. But I've been to recent M&Gs in other cities. The ladies usually come dressed to impress. The guys not so much.  The host/hostess sets the guidelines. as to behavior, lots  of mingling. I've set up future dates at M&Gs and even met a provider after a M&G.  If your expecting an orgy,  It ain't gonna happen. You'll get a better  idea of what to expect when the venue is announced. Some hosts/hostess will give a brief list of do's and don'ts when the location is announced.
