Boy can this all get confusing or what!!
I voted that we are Swingers but we use the term lifestyle or lifestylers also. For the swinger term I'd define us as having sex with couples (mostly) and singles. We, by OhioCouples found definition, are not lifestylists in that we are not "devoted' to swinging.
We use 'lifestylers' to define the fact that we are swingers and prefer to widen our field of friendship to include more swingers/lifestylers. We feel more ourselves around swingers and people in the lifestyle so to speak whether or not we actually "play" or are just good friends. There is a certain freedom that you have in conversation etc. with lifestyle friends that you don't and can't have with anyone else (i.e. co-workers, family, vanilla friends).
Anyway that's my help on confusing the definitions even more
