There's a section in Dan Savage's wonderful Skipping Towards Gomorrah about a swinger couple that is very religious, has three children, and are madly in love with one another. They don't bring their "extracurricular" activities into their home. They go to clubs or conventions in the city near their home. People here should read that book...and then start reading "Savage Love." Dan gives WAAAAY better advice than Prudie when it comes to sex/relationships.
