Sounds like you are off to a great start! Successfully getting into swinging, and reaping those rewards that you already seeing, has a lot to do with how one goes about it, and you're doing things right.
My advice would be don't let any one thing, positive or negative, sway you far one way or another. Example being the single guys at clubs. Instead of letting that turn you off to the whole thing, you just rolled with it and learned from it. That's the way to do it, never get too up or too down over any one night or one thing that happened. After a little time experiencing different things, you will have found the swinging style that works best for you and you can kind of focus in on that.
It's always awesome to hear from someone new about how things are going well and the positives it is bringing to the relationship. Those of us that have been doing this a little longer well remember when we were new and experiencing the same things and it's nice to get to relive that again through someone else's eyes and feelings!
