Well - there is certainly enough grey area for everyone to find their kink - I suppose...
Like you guys, though, I think if I knew it would really kind of curdle the milk, so to speak...
Mrs Spoomonkey feels like the inherent risks of swinging needn't be brought into the period of pregnancy - and I agree. I think you guys were wise to not swing, but I am sure others could make a case for why they chose to continue.
But - I know that rules that make good sense can be "adjusted on the fly". For example, we have a rule that we only swing with married couples - but we have already adjusted that one. We're not terribly glad we did, but we did. I can see this being one of those grey areas where we meet a couple we really are attracted to and the mountain becomes a mole hill.
But - giving room for our "impulses" and "imperfections" - we agree that people should probably postpone the lifestyle while pregnant. But that is hardly a thing we'd expect everyone to agree with. As you said, whatever tickles your pickle... And when it comes to my pickle, the tickle usually rules...
