I don't think it's "almost a breach of trust", I think it is a breach of trust. Your friend agreed to the rules when you all got involved. One person should not force the issue of advancing the relationship on the rest of the group. You all agreed how to proceed and it should be a group decision to advance to the next level. If one person is uncomfortable, everyone should step back and slow down. I think the idea of moving at the slowest persons speed works in this situation.
I would suggest talking to your friend in a neutral location. And not during a swinging encounter. Try to get him to see how uncomfortable you and your wife are. Be sure to let him know that if and when you decide to advance to a new level of swinging, you'll let him know. But at this point in time, you and your wife are happy keeping the status quo.
Good luck. I hope all works out for you. Let us know what happens.
