F half of MF. New to everything and would appreciate some enlightenment😅

1.) Is swinging mainly couples being involved with other couples? Or is it a broader spectrum than that? My husband doesn’t want another man physically involved in any way. That being said, I want to make sure I am looking for connections in the right place.

2.) Does anyone have experience using fetlife? I find it more confusing than Reddit. Idk how to meet people with similar interests near me. And don’t you dare mention using apps. I’m on 3fun, down, and feeld. But it is slim pickins in my surrounding area and no one wants to build a connection long enough to feel comfortable to travel. Everyone wants a hookup or a date and I can’t find anything within a 50mile radius. I’m impatient.

3.) Are casinos a good place to meet like minded individuals? I’ve seen it mentioned here and there a few times. I’m celebrating my 30th soon. Would that be a good place to go?
