not for everyone, but with the right mix of people and they can be a lot of fun...basically so long as everyone understands before hand what's what then there shouldn't be any issues to get over...:2 cents:
We talked about it for years, then, in our late twenties we went to a swingers' club, rather nervously, just to see what we thought of the atmosphere and maybe watch people in action. We liked it so much that we started getting together with other couples that first night.
We're now in our early forties and have enjoyed lots of swaps and trios. There are no issues if you both want to do it and you get together with nice strangers in such clubs.
The issues arise when you know the people from you normal lives, or if you get to know them, that's when jealousy, embarrassment, gossip and tensions can become a problem.
