To answer two questions.
Swingers are open to EVERYONE. If your wife doesn't want a man's advances, she says "NO". And that's it. Anybody who doesn't respect NO is usually asked to leave. I've never seen that happen.
To find other swingers, duh...Google swing clubs in your town or region.
Some are clubs ("off premises"

where you just sit and have a drink and look around at the other couples.
If the two of you see yourselves being smiled at by a couple whom you both like, invite them over with a nod, or send them a drink.
Introduce yourselves and see if the spark ignites.
Then decide where you're going to go.
At "on premises" clubs, it usually starts the same way, or in the Jacuzzi.
You both might need a couple of drinks to erase the fear and loosen the inhibitions.
At on premises clubs, the action goes on and on and there is a lot to choose from. If you just meet a couple at an off premises club, it's just the four of you, unless they or you want to invite others to your session.
The last one I had, we met three other couples and we all left for our house and we all had each other twice.
