Where I live it is very difficult to find ppl with an open mind. We have had a lot of experience conjuring new ways to "make contact". Of course it depends on how you two feel about going out on a limb. One way we have had some luck is at a bar or party, you sit in a corner or whatever and have your wife do some flirting. Whether it be with a man or woman the 3rd almost always seem more comfortable with the woman doing the "negotiations". It doesn't just have to be at a bar my wife has flirted with ppl at work and through various websites. The thing is though we have had a few "on the line" we have not "landed" as many as we hoped for various reasons. Most importantly talk through it with her and keep pushing for the common goal.
