My wife and I are a typical heterosexual, she is open, we a couple, but we have a dirty secret: We're swingers. No, we don't twirl and flip to music from the 1940s; we meet other couples and have sex with each other's partners. Due to our conservative careers and even more conservative families, we keep our sexual practices to ourselves. Only a few close vanilla friends know what we're into ("vanilla" is the term swingers use to refer to anyone who isn't a swinger ... and also other swingers who happen to be covered in vanilla).
