Yep, my wife and I think its great. Hooked up a guy through a swingers site but it didnt end up the way we liked it. You would be surprised though just how many guys didn't want to go through with meeting up when it came down to the crunch. We now 'shop' around at clubs and bars, although its a bit harder because some guys want to know what the story is.
I say if you find a willing girl who is up for it then give it a go.
Good luck!!
