Keep in mind that just because another couple is in an AGR, it does not necessarily mean they will have something in common with you and your girlfriend.
What if you find a local AGR couple, but they are into traveling, fine art, and wine-tasting, while you and your girlfriend would much rather get together at home for a game-night complete with beer, nachos, and NFL?
I think you should focus more on finding couples with similar interests, rather than similar ages. If another couple should be in an AGR, just consider it icing on the cake!
