Rules are often set between partners prior to "swinging". "No means No" is a rule that ALL swingers should follow. But other rules can be set about respect, jealousy, privacy, and even code words or signs.
Many swinging couples start out in the club scene. This allows you the opportunity to look without being involved, in most instances anyway.
"Swingers" can be found in every race and profession. All levels of education and ethnicities are present. Most swingers, however, are Caucasian, middle to upper middle socio-economic class, and married. Both married and unattached "swingers" often tend to be venturous, sophisticated, and social creatures. Most single women who join swing clubs find them to be a revitalizing substitute for the usual bar scene.
