I respect anyone's choice to go the swinging route. My thought was that if the OP's problem was with his wife being in love with someone else, swinging might seem like a good plan because it would sidestep that issue. But when we see so many stories here of people who thought they were just after sex and then freaked out when they fell in love, I wouldn't consider it a solution because there's no reason for us to ssume that Barbie can, in fact, separate sex and love.
It occurs to me though that I may be way off base in my understanding of the situation. I'm not sure now what exactly made me assume the emotions involved were the problem. Ken, what was the source of your discomfort with Barbie and Stewie's relationship, taking June out of the picture for a minute?
