Welcome to the forum and yes I agree that you are in the right place.
I am responding to your post because my wife and I are in the same situation with another couple. We did not start as swingers mind you but that doesn't matter anyway. Your current situation relates to ours almost exactly. Dates, overnights, statements of love... between secondaries. Yes its a lot of fun and very challenging emotionally at times.
If you wish to chat further please message me directly. I came here to learn from others in the same situation. There aren't that many compared to other configurations but I have made a few great contacts.
