i also suggest the gym as a good place for your wife to meet friends.
My wife joined a gym about 3 years ago and that's where this lifestyle started for us. We had talked about her being a slut and cheating, mainly as dirty talk during foreplay, since we married in our early 20's, before I even knew what a hot wife or cuckold was. After about 10 years of marriage, i told her i was OK with her playing with others, and that i would enjoy it. of course she was concerned that I wanted to cheat and she was concerned i was testing her. After a long while and lots of pillow talk and fantasy play, she realized I was sincere. But, she was still not ready to do something like that for real. She always said, 'i love the fantasy, but don't think i could ever do it for real." And I was always supportive and also kinda relieved but always wished she would be a naughty slut behind my back or with my knowledge. in the mean time, we have had 2 kids, and my wife of course put on baby weight and got chubby around the middle. She was having a hard time losing the weight, was feeling depressed about it, feeling low self-esteem. She was now in her late 30s. So we discussed it and we joined a gym together since I was getting older and flabby
too. I worked out for a month or so, and got lazy. My wife enjoyed it and stuck with it. She lost some weight, got fitter, and started to feel a lot better about herself as she fit into old clothes she thought she would never wear again. We started having sex more and more, and our dirty talk almost always centered around her being a cheating slut wife. I reassured her that it was my fantasy that she play with other guys, and she reassured me that it was just a fantasy.
One Saturday afternoon, while we were eating a healthy salad after her work out, she told me this muscle head guy got on the elliptical machine next to her and started chatting with her. I believe she told me this because she was feeling guilty about chatting with the guy, and speaking about it openly and innocently with me made her feel less guilty. When she told me, I felt a pit in my stomach, and I got hard. But, I just giggled and told her it is natural for guys to want to talk to her. I told her you can't blame a guy for trying to chat up a beautiful woman and I left it at that. I banked the little tidbit and immediately figured i would bring it up during our next foreplay session.
Long story short: We gradually got to a place where she was ready to play, and she has had a couple of good experiences from the gym. So, I definitely think that is a superior place for a woman who is ready to play. Much better than a dance club with takess and loudmouths.
