[4sum]

Two questions:

(1) How many couples out there swing exclusively with one other couple? And if so;

(2) Does the realtionship ever cross the infamous Love line?

Here's the deal. We've been pretty much an exclusive 4sum for about 2 1/2 years. Fairly early on we decided that we were willing to make an emotional commitment to each other as well as just having a good time physically. We're intelligent professional people as far from new agey granola chewers as you can get, and haven't been seeking to "replace" our spouses. It seems to work pretty well, and hasn't been an incredible imposition on our relationships with our spouses since we keep it all in perspective. Just wondering if anyone else has experienced a similar situation.
