Thought I was specific enough...
You might very well have been. I have been known to misread. I'm glad that things are balanced, though.
I understand that insecurity of approaching people with "Hey, my wife's ok if I sleep with you" or whatever variety that takes.
If this helps at all, I have unconsciously attracted many "open", "poly" type lovers in the past, simply because that's how I'm wired. I'm beginning to find it amazing how many people that I've clicked with have ended up being poly to some degree.
Like attracts like. Maybe you will begin attracting people who will already be open to this lifestyle and it will evidence itself in some kind of organic unfolding, rather than the awkward approach??
Hope that's a help...
