A lot of the five years we spent talking about swinging before we actually did anything were actually periods of not talking about it of course. Red needed the time to digest the idea and work out just what she thought and wanted. Let us simply say that it worked for us. When the time was right and Red had decided she really did want to give it a try, all the potential problems had been well ironed out and we have had no significant problems ever since. Just lots of fun
So my advice would be to let your wife have her thinking time. At some point no doubt there will be suitable occasions for you to mention it again, but above all, don't push it! That would probably be a mistake. In all probability she will mention the idea herself when is is ready to do so.
